I would not know... I am not much of a gamer. I bought my Macs to use as tools. I use a windows emulator to run the only MS Windows program I own, Flight Sim 2000... because it is not Mac supported...
I also use Office and wish I had a good alternative... besides that, I only use Mac compatible programs. My wife picked up one of my QuarkExpress CD's, and loaded it onto her G3 PowerBok. She sat down and built an eBay design in a couple of hours with no training, other than her Mac acquired skills... All of Mac programs usually use the same keystrokes, the same linear function, and GUI. The programs are more intuitive in their uses, and act as if they are built together with the OS.
You would think that Apple planned it that way! (sarcasm off)

"because it is not Mac supported"
is a very long list.
