There are games available for the PC only if I recall..it has been awhile since I have even looked.

There are thousands more games on the Windows-side! And it seems only the top sellers will eventually make it to the Mac-platform. And that in spite of the gradually increasing market share of the Mac. Also, some game developers (e.g.: EA) indicated that they would release games on the Windows and Mac platform simultaneously. That has happened a few times but is still rare.
The best solution -IMHO- to play Windows-only games on the Mac is 'Bootcamp', even though you may be hampered by the crappy video cards in some of them.
