This reminds me of Scribblenauts. There was an interview with one of the devs at the E3 before it was released and he discussed how much time went into the game simply to pad the internal "dictionary" and conjure up not just things, but also make sure that those things could interact with other things (e.g. "bread" should be able to interact with "toaster" to make "toast").

I don't remember if it was the dev talking about his own team, or if he was talking about players interacting with the demo, but he mentioned that some people were attempting to summon a list of ingredients (flour, eggs, sugar, milk, etc.) and throw them into a bowl and then into a heat source to see if they could make cookies within the game.
