Games via gamers

News.com's "Tomorrow's games, designed by players as they play" talks about how games are letting users do more inside the game. Sims allow users to create their society/environment while The Movie allows one to shoot any kind of movie. More controls are given (back) to the users but it isn't to the point where the users are changing the programs. The closest is the game modding but that's only on the "surface" of the games.
