Great game if a person has the hardware to run it.
As of update 7 it introduces 3d hardware acceleration for both 68k and ppc. Along with that it adds things like screen rotation. It really is quite different a game depending on updates applied and a persons hardware. PPC versions adds next to nothing apart from a little speed. Mac version is very similar, only it started out life as already having updates applied. Main difference is it doesnt suffer from the blur-o-vision that plagues ppc amiga systems versions of gl.
