"More important: the game, Sand-dancer, is a good game. It is not the sort of example that exists to have one of everything in the manual. It is the sort of game that exists to make IF better. Aaron puts it together on your workbench. You can see the parts going in, and I don't mean rules and action constructs now; I mean character, background, voice, theme, and narrative drive. He explains what he's doing, and what each game element is for. He talks about story structure and shape of interactivity. He discusses what you have to do to get the player involved and what you have to do to put the player in control." This sounds great. Add-to-cart.

"I want all the young present-tense storytellers (the old ones have won prizes and are incorrigible) to allow themselves to stand back and show me a wider temporal perspective. I want them to feel able to say what happened, what usually happened, what sometimes happened, what had happened before something else happened, what might happen later, what actually did happen later, and so on: to use the full range of English tenses." There's lots in here. I think it might be good; it is definitely interesting, and worth returning to.

"In this programme we hear from colleagues, friends and former students as well as the great man himself about the beauty of nature and the importance of science to our understanding of the world." A lovely Archive Hour on Radio 4, on Richard Feynman; only available for a few more days, so grab it whilst you can. Delightful, and nicely structured.
