Spore Gameplay Video. Wil Wright's new game will change the world. Watch all 37 minutes of this talk, then aw with me as the video cuts off the end of Wil's presentation.
I actually can't tell if the game will be fun, but the user-created content aspect is one hell of a takeaway from this talk. Wil emphasizes that this is not a multiplayer game, yet it uses the Internet to communicate with other players to drop stuff they've built into your universe. I want to know if the game uses a fitness evaluation to establish difficulty ratings for user-created content and level my universe according to my own progress. (At first glance, Spore probably doesn't need such a feature, but I can't tell without playing it.)
