I reckon your success with Cedega will depend on your game selection. So far, I've had wonderful luck. I just finished Jedi Academy in Cedega. I have the original Rollercoaster Tycoon (gotta love the bargain bin) running fine after following the directions in the game FAQ. I'm playing through Knights of the Old Republic now. I even have GTA: Vice City playing in Cedega, though I am not happy with the sound.
