I haven't tried any games, but before I got Quickdraw 3d working I used Photoshop 4, WordPerfect 3.5, an anacrostic generating program, and Print2PDF, with great success.

Since getting QuickDraw 3D operational, I run Infini-D 4.5, the last release of Meshwork, the next to last release of Geo3D, and several of the Apple legacy tools, including TextureEyes, 3D MovieMaker, and MakeObjectMovie, (and Gerbils!) also with great success.

One of the guys over on the E-Maculation forums has quite an extensive list of stuff that he's tested.
