Things to consider:

* Genre? RPG? Top-down shooter? FPS?
* Framework? My vote is SDL, though I myself am currently using C++ and SFML and really like it.
* Graphical style? Who's going to do them (I can't draw for my life)? What about other artistic areas, such as sounds and fonts?

I'll be happy to contribute (though my C is lacking and tackling a game without OOP is going to make me sad), give me a bell whenever. For learning general gamedev and SDL, then I'd recommend the Lazy Foo tutorials, though they are C++ (can't remember how much of that matters though).

Also, thanks for using my title! :P
