This is super-good – not just on ARGs, which aren't necessarily flavour of the month, but on designing difficult puzzles for a large number of people to solve, and how not to be surprised by how fast groups are at solving things when they have the network. Gating the experience with slow tasks – MD5 brute-forcing, for instance, is one nice idea; I also really like Adam's points about making sure players know precisely what is in-universe and what isn't, so there's never a question of whether something is right or not; just like a good cryptic crossword.

"If we were managing a brand would we have been so brutal and focused with these things? Probably not. It would have been someone's job to think of these as valuable brand assets and argue for their preservation. For some reason, as soon as you describe something as a brand all this fake science marketing mysticism gets invoked and paralysing decisions get made." Russell on GOV.UK

Hello Lamppost ends up on the Creative Review blog.

"I would call him the greatest puzzle designer of all time, but that implies that there are lots of people who do what he does and he’s better than them, and that’s not quite right. What I mean is to say is that Raymond Smullyan is the Marcel Duchamp of puzzles, he’s the Brian Eno of puzzles. His work is singular, transformative, genre-defining, in a class by itself."

"It’s a bit like augmented reality, a layer inserted between what leaves the server and what hits your brain." Yes. Also: see Ben's comment about the browser as weapon.

Alan is writing the Guardian's crosswords blog, looking at crosswords from all publications. Brilliant.

"The puzzles [in Limbo] aren't brain-busters, and even though you die a lot, it always puts you right back where you started. It's just so capricious. It never bothers to set limits or rules for the world you're in. Its sole concern seems to be killing you for no apparent reason. Instead of asking you to apply what you learned from your previous deaths, the game keeps changing the rules so it can kill you again. It's as though it's making things up as it goes, like a rambling first draft that could use a good revision."

Now that Net Yaroze has closed its doors, Edge catch up with some former Yaroze developers; they have some interesting things to say on the state of games education in particular.

"[Our heroine's] name is Marta Louise Velasquez, and she’s quite possibly the most unpleasant female lead character in the history of gaming. She’s also what makes TD2192 worth remembering." Indeed, I have many. She did not lead a happy life, I'll give Richard that.

"Critical thinking is the key to success!" Professor Layton is on Twitter. Officially. This is good.

why do it? To borrow from the site's About pages: "First, it will help you find shows that others have not only watched, but are talking about. Hopefully it'll throw up a few hidden gems. People's interest, attention and engagement with shows are more important to Shownar than viewing figures; the audience size of a documentary on BBC FOUR, for instance, will never approach that of EastEnders, but if that documentary sparks a lot of interest and comment – even discussion – we want to highlight it. And second, when you've found a show of interest, we want to assist your onward journey by generating links to related discussions elsewhere on the web. In the same way news stories are improved by linking out to the same story on other news sites, we believe shows are improved by connecting them to the wider discussion and their audience." Dan Taylor explains Shownar from the BBC's perspective

"Shownar tracks millions of blogs and Twitter plus other microblogging services, and finds people talking about BBC telly and radio. Then it datamines to see where the conversations are and what shows are surprisingly popular. You can explore the shows at Shownar itself. It’s an experimental prototype we’ve designed and built for the BBC over the last few months. We’ll learn a lot having it in the public eye, and I hope to see it as a key part of discovery and conversation scattered across BBC Online one day." Matt talks about Shownar on Pulse Laser.

"Shownar tracks the online buzz around BBC shows. It's an experimental prototype and we want your feedback." What I've been working on in the first three months at Schulze & Webb, and is now live. Exciting!

"…even if they make the rules explicit, it’s not going to help the “power-leveling problem” which is ostensibly the reason for all of this grief. Unless they remove all difficulty options from the system, there will always be easier and harder ways to level. And remember what I said above: users tend to prefer easier content with better rewards. This isn’t limited to user-created content — it’s true for designer-made content, also. But designer-made quests don’t get graded by the players. Player-voted content like this will always gravitate towards easy. And pick-up groups will always be picking the most rewarding content with the least annoyance. And the game devs will keep being unhappy about it." Smart analysis of the problems with City of Heroes' user-generated missions.

"Games don't separate learning from assessment. They don't say "Learn some stuff, and then later we'll take a test." They're giving you feedback all the time about the learning curve that you're on. So, they're not the only solution to this problem by any means, but they're a part of the solution of getting kids in school to learn not just knowledge as facts, but knowledge as something you produce; and in the modern world you produce it collaboratively." Jim Gee is a smart guy. I need to read more on him.

"I suggested that, when it comes to the design of embodied interactive stuff, we are struggling with the same issues as game designers. We’re both positioning ourselves (in the words of Eric Zimmerman) as meta-creators of meaning; as designers of spaces in which people discover new things about themselves, the world around them and the people in it."

"Statisticians’ sex appeal has little to do with their lascivious leanings … and more with the scarcity of their skills. I believe that the folks to whom Hal Varian is referring are not statisticians in the narrow sense, but rather people who possess skills in three key, yet independent areas: statistics, data munging, and data visualization. (In parentheses next to each, I’ve put the salient character trait needed to acquire it)."

Ron Gilbert plays The Secret Of Monkey Island again, and takes notes. Nicely measured – neither grumpy nor jubilant, it reads like an interesting director's commentary. Good stuff.

"This week I've killed Steven Spielberg three dozen times. I'm feeling better about the whole thing now, so I'm not going to vent any more steam about his increasingly asinine – and frankly pretty arrogant – repetition of the 'games won't be important until they can make you cry, which up until now they haven't been able to, but don't worry I've come to fix things' line." Which, you know, is good, because it means Margaret can talk about the joy of cubes instead. Or Cube, to give him his proper name. A wonderful One More Go, this week.

"Anecdotal feedback also confirmed that without exception, the PSP was regarded as the best sales presenter ever received. As a result, Foster’s is now reviewing further rollout of the tool." Fosters use a pre-loaded PSP as sales demonstration tool; it does very well.

"Each world has a specific mechanic and overlapping rarely occurs between world mechanics. Instead, the player is given just enough objects on the screen to solve the puzzle with the limited tools available. By being able to concentrate on one mindset of solving the puzzle, eventually the solutions make themselves apparent." A nice Manveer Heir piece on why the puzzles themselves in Braid are good: because the game creates complexity out of limited tools, rather than throwing every mechanic in all the time.
