Don't say 'Deus Ex' or 'Unreal' because I am looking for something playable on my wimpy (in the gaming area) iBook, in OS X.
I tried the Quake 1 port, but it was a no-go. Can't get it to start up at all. Too bad since I was really excited about that one.
Are there any FPS games that will run well and still use the graphics chip, or OpenGL? Keep in mind that even in OS 9, Unreal is a little choppy on the iBook 500, so it needs to be much less graphics intensive than that.
