"AlterEgo is a Ruby implementation of the State pattern as described by the Gang of Four. It differs from other Ruby state machine libraries in that it focuses on providing polymorphic behavior based on object state. In effect, it makes it easy to give an object different “personalities” depending on the state it is in." Oh, that could be really handy.

Oh gosh this is brilliant.

"Simply stick your finger in the hole and a virtual representation appears on the screen. Then you can use your virtual finger to play all kinds of cool mini games… from swinging a panda to having a karate fight with a tiny little man." Um, wow. Although I'm always afraid of putting appendages in boxes I can't see inside, though.

I think they're wrong, you know. It's not theatre; it's protocol. Maybe people aren't used to the protocol; if yours is the first app they encounter, they'll think that it's OK to show what passwords are – and perhaps that it's OK to write them down elsewhere in plaintext. Applications have a degree of responsibility for users' interactions across the internet, and quirky and cute as this may be, it's just not the place to demonstrate your shining personality.

The Brian Dettmer is beautiful. Also: didn't realise the heart/cube cogs were paper, not wood.

"…it's another little example of the way the ipod/iphone is such an attention-demanding device. It doesn't orient to you, it orients to itself." Yes. This is a problem.

"The US auto industry is on the verge of imploding. People are losing their homes to foreclosure. And, on the off chance that you had the nerve to try to buy something, credit is almost impossible to come by. It is against that backdrop that I would like to talk about working for free. Why? Because I think it is one of the fastest ways to make yourself a better photographer, whether you are a pro or an amateur."

"To the extent that the web is becoming truly ubiquitous, and involves increasingly multimodal paradigms of interaction, it seems appropriate to define a Web standard for representing emotion-related states, which can provide the required functionality." No, it does not seem appropriate. It seems bonkers.

Hey, I've been in that relationship too! These made me laugh a lot.

"bill. francis. louis – look here. help." Ah, the fun of the farm. It's all coming back to me now.

"It’s easy to roll your eyes at the people who look at an Xbox 360 controller or Dual Shock and say it’s too complicated. “Left 4 Dead” proves there are hardcore experiences — not just Wii and DS games — that can draw them in…but the controller remains a challenge that won’t be easily overcome." I'd never roll my eyes; modern pads are very complicated, and twin-stick move/shoot is one of the hardest skills to acquire. Still, a nice piece of commentary on what learning to use a controller looks like, and a healthy reminder.

"So when I play Fallout 3, and I think this is probably true for most people who are over forty, some part of me is always wondering if this is what it really would have been like. Not in terms of enemies, but in the way that humans banded together into small groups to create enough order to survive." Bill Harris on a perspective on Fallout 3 that I'll never have.

Click "CM Gallery". Watch. In order to illustrate the xiao's ability to not only take but also print photographs, Takara Tomy really pushed their anthropomorphic metaphor to the limits.

"Yes, it's true that at no time while playing Prince of Persia did I feel any of the frustration that I felt on a regular basis in Mirror's Edge. But neither did I ever feel the joy of doing something right, of stringing together a perfect series of vaults and wall-runs and feeling like it was based on my own skill. Can one exist without the other? Is it impossible to create joy without difficulty? I don't know. But Prince of Persia lost something significant." I'm a bit worried about the new Prince, especially having read this; the challenge/reward balance is hugely important to it as a series, especially since the marvellous Sands of Time. Also, more worryingly: are developers shying away from letting players fail any more?

"The Facebook Republican Army, based on Brighton's tough Whitehawk estate, looks for parties on Facebook. The gang boasts it travels nationwide – and has even bought its own coach." Oh boy.

"As the about page says, if you live exactly 6 minutes from Sunset Tunnel East Portal, 8 minutes from Duboce and Church, and 10 minutes from Church Station you may find it useful too." Bespoke tools for yourself that might happen to be useful to others. I like this a lot.

"The Firefox add-on "Pirates of the Amazon" inserts a "download 4 free" button on Amazon, which links to corresponding Piratebay BitTorrents. The add-on lowers the technical barrier to enable anyone to choose between "add to shopping cart" or "download 4 free". Are you a pirate?" Almost certainly not the first example; perhaps one of the best realised.

"That's how I got here. How long will it be before someone builds a raft and sets sail in space? Bill Gates has over fifty billion dollars. What if Richard Garriott had fifty billion dollars? If he wanted to, would that be enough money to build a rocket to get him into space, and a self-sustaining environment in which he could live? Would he want to sail away and never come back? … No matter what happened in our future, [whoever built that raft] would forever be the first. A thousand years from now, people would remember his name." Bill Harris is awesome.

"The Whale Hunt is an experiment in human storytelling." 3000+ photographs, with what seems like a confusing-and-shiny interface to explore them – but hides a detailed metadata manipulation layer underneath. Beautiful pictures, too. Something really quite special; the "interface" pages should explain more.

"Still, overall, Left 4 Dead's opening cinematic is a shockingly complete primer to the rest of the game. With only a few exceptions, almost any player going into Left 4 Dead for the first time will know exactly how to play the game: they already know the gameplay, the weapons, the enemies, the win scenario and the strategies they need to get through the game alive… the only thing not covered in the opening movie is the specifics of the interface." Yes – had this exact same conversation a few days ago. Although John is awfully down on Louis, which seems a tad unfair…

"The obstacles that exist are mere impediments to my motion, puzzles placed only to slow me down or stop my free-flow kinetic improvisation. No time to think or overanylize, only time enough to move. This is what the essence of gaming should feel like: a sincere, wholehearted attachment to the action (or actions) that one sets into play. It is a moment where the motivation at hand is intention only, whose aim is exploration and discovery, refined. It is the escape, distilled and realized." GWJ on Mirror's Edge, and never rewinding, never looking back.

"Metro Rules of Conduct is a game about the awkward situation of commuting in my hometown, Stockholm. Look at mobile phones, MP3 players and breast for score, but whatever you do – avoid eye contact!" Wonderful; the art-style works really well, as does the head-bob.

"Melville was torn between writing a ripping nautical yarn and a metaphysical odyssey, and it shows. Rockstar was torn between constructing a sandbox and a stage, and it shows. The result was a tenuously fused work of genuine Americana: a disorderly paean to the American city, a bit of ultraviolence, a stonkingly beautiful soundtrack, a fable, a simulation, a gonzo critique of capitalism. It's a game we deserve. " Pliskin on what GTA4 meant. Perhaps hyperbolic, but it's an important signifier of this year. The Redding quotation about Far Cry 2 is also a stonker.

All 226 entrants for the 2009 IGF. Heard of – and played – some of these, but many are unknown. Exciting to see the list, though, if only to be reminded that there's this many games being made and funded independently, at the large and small scale.

"aphex twin + vassily kandinsky + doom 2" – now that's a tagline.

Lots of (large) images; detailed, wonderful. A post to go back to and pore over

"I must admit that I would have loved to get this richness of backstory into the actual game itself, but the longer pipeline of game asset development and integration made that impossible." Clint Hocking explaining the background behind the fictional blog for Far Cry 2.

The blog of Reuben Oluwagembi, the fictional journalist you meet in Far Cry 2.

"A few weeks ago we released our shapefiles via the API, and while most people were excited, some folks were a bit confused about what it all meant. Which is why Tom Taylor’s beautiful Boundaries application is so exciting. It helps you visualize the Flickr community’s twisty changing complex understanding of place." Tom is on code.flickr.com! Hurrah!

"Renaissance ‘lace books’ have much to offer the modern digital designer, who also faces the challenge of portraying clear and replicable images in a constrained environment." A brief history of pixelfonts.

"Obama's FCC transition co-chair is a WoW player, and has played in two different endgame guilds, including Joi Ito's famous We Know guild." This is exactly the kind of thing I was banging on about at Gamecity. Presentation online soon!

"We're still going through the stats, but at the time of writing there were almost 170,000 messages on the Strictly [Come Dancing] board." Holy hell. Poor moderators. (And: for such an uninteresting story, as well!)

"If the Barack Obama presidency fails to unite us as a country, I'm going to hold out for a fast-zombie apocalypse." Iroquois on co-op, and the way Left 4 Dead sees online co-op – and the bad behaviour of players online – as design problems to solve, rather than to ignore.

"Who designs a character for gamers to never go near? Who spends the time to create the most terrifying creature imaginable, and doesn’t impose it on players? Well, clearly Valve. The temptation to have her be aggravated from great distances, to force her to attack when encountered, must have been there. But then she’d have lost her power. Her power comes from just sitting there. It’s that benign, ragged, vulnerable form. It’s the combination of singing and crying. Oh God, the singing *and* crying." John Walker examines the horror of Left 4 Dead's Witch. A little over-written perhaps, but he totally nails the fear the character instills, and the way you always notice her a split-second too late.

Mitch just isn't inspired by user-generated content, no matter how charming a core game might be. The comments thread on this one is really good.

"The next generation on from them – e.g. Jonathan Smith, Doug Church and of course Greg Costikyan (from whose classic essay on developing such a critical language the title of this post is lifted) are always eloquent, passionate and insightful speakers and spokespeople for their medium. Unlike Molyneux." Not too annoyed I missed this, given Matt's comments.

"…the players are there for their character, not for your story. Your story is just the path for their characters, the medium through which they can play their persona. Once the GM realizes this, they should then realize that respecting the player and the character is paramount to their story. And it’s a surprisingly easy skill to master, because it really is as simple as recognizing what the players and characters want, what they came to do and then give it to them."

"Demeter quit his bank job two months ago and has launched a company, Demiforce, to develop more electronic games. Now he has a salaried staff, five games in development and two coming out by Christmas, including a spinoff to "Trism" called "Trismology."" I hope his success continues; scaling up always seems scary, but Trism was – and is – superb.

"The conundrum is that no path, no vision of progress – technological, social, moral – will be plausible today if it does not include the complexity of costs, yet it will not be desirable if it does. That makes our society blind." Some good, if dense, Kevin Kelly.

"I wrote a script that lets you see what this money could buy if we weren’t throwing it at second-rate comedians or third-rate bankers. What if we spent it on schools, or teachers, or wispas instead? My script lets you see that by altering the text of Guardian articles as you browse." Ben's hack was brilliant in its simplicity, and really does change the way you read the news.

"Turf Bombing is a location-based turf battle game which rewards and encourages traveling and learning about different neighborhoods." Location-based game that forces you to travel out of your normal areas, and potentially explore transport networks. Also: not designed around specific devices, just laptop+wifi.

"Fallout 3 is a tribute to intent. It's not a rallying cry for any cause or even a cautionary tale about the hypothetical horrors of nuclear holocaust. It's a statement on the worthlessness of inaction. It's about not staying in the vault."

"Far Cry 2 doesn’t so much attempt to define a memorable experience and effectively communicate it to the player as it does to define a set of rules and an environment in which memorable experiences are likely to happen, letting the player loose in that world." One of my favourite pieces of writing on FC2, if only because it captures the nature of the game so well.

"Oddly, although Left 4 Dead only comes out today, Gamestop.com has already switched from their previews to reviews. You'd think that wouldn't be enough time for their users to appraise the game. You would even think that they'd want to play the full game before trumpeting their thoughts and throwing around phrases like "game of the year." You would be wrong." Mitch is harsh but fair.

"See what's been discovered by the Wasteland inhabitants!" Collaborative slippymap of what people are finding in the DC Wasteland in Fallout 3.

"Images don't automatically attach to emails. I hope you and your husband can work things out though." Oh dear.

"For all the prioritizing and severitizing (which costs a lot of time during bug input) the best method of bug sorting was human communication." Yes. Too much time has been lost in too many custom installs of JIRA.

"Hi everybody, I'm Brandon, and this is Offworld." Oh! This could be good.

"These concepts are not complicated by Cern standards. We are entering a zone which is weaponised to boggle."

Simple, straightforward, pretty much correct.

Yes, this is going to come in handy.

"This javascript function can then read in the current content of the text area, format it using a trimmed down version of textile, and then set the content of a DIV with the resulting HTML. The end result of all this is live comment preview, with textile formatting." Live textile preview functionality.

"Trying to over-explain the cause of a disaster often detracts from its more tangible impact. … Instead, Faliszek says, it is more effective to create resonant gameplay experiences that players will remember, particularly if the setting in question, such as a zombie invasion (or a tornado outbreak, for that matter) is already familiar." Why games don't always need tangible villains.

A nice approach to doing some of the typical monitoring you'd want to do with Google Analytics, eg monitoring PDF downloads. I'm not totally convinced by some of his syntax, but the functionality is good, and the regex trick is nice.

"It's just an Nintendo in a toaster, but I like it."
