Well, I'm gonna try to make an FPS only using Ken Silverman's Evaldraw. For those of you who don't know what it is, it's basically a real-time compiling programming environment with a built-in 3d engine. It's very old, you can find it here : http://advsys.net/ken/download.htm
. Anyways, I think the only real problem I'll be having is *shudder* collision detection. So I'll see what I can do.
