I really think that it needs to be deeper than a speed game.
I still believe the cdn project x would be way more effective. The idea of making several games under 1 theme, so that rpgs, card games, action, strategy, and all others can be made from it. a pool of graphics, storys and things would be built up, so that a person could make games with the information.
what happens is can do many games by many groups, not everyone works well together. and to big of groups can be dysfunctional.
make it a community project? where people can work within a area and way there comfterable. while still making games they like. the best example of this is starwars, you have developers making lightsaber duel games, have space based games, infantry based games, command and conquere based games, rpgs, card games, they all use the same characters, ships, technology, and the games feed eachother fans. each game feeds the project more and more. more music, more graphics, more character content, more stories. so theres information about it in all areas. and the games take what they want, use a game from it. which may expand or may not expand the project. but any game generates more intrest and in the long run helps the project. like a person takes all stuff like graphics, music and stuff makes a game with it, maybe its humorus and mocks the projects characters. like it spoofs everything that also proves funny and helps the project.
