3D Games

If you're looking to make 3D games on a Mac there is no better tool than Unity. It's easy to use, with a great GUI and all the scripting done in the familiar javascript. You can use it to build games for OS X and Windows. There are also plans to make Wii and iPhone builds possible. It costs $200 to buy the indie licence, but even if you can't afford that it is worth checking out the free 30-day trial. If you need a free alternative Dim3 is a popular open-source 3D engine. My own experience with it is fairly limited but, while it is certainly not as easy or powerful as Unity, it looks to have some potential and is certainly worth looking in to.
