Look into Wine and Cadega... Wine is free and always in a constant state of development. Cadega is a one time fee (I believe) of around $30. Haven't tried Cadega yet, but have heard that there's a lot of Windoze games that run great under Cadega... I have limited experience with Wine, but have heard that few games (openGL and DirectX) will run on it.

I am just about to try and install AFPD with wine, I'll report back on any success/failure when I eventually get around to it.

HTH,
