GMAX  IMO, not worth $20. Registration hassles are a deal breaker.  (Version 10.5)

XYPHER  Wish they'd updated Real Pool for OSX. That's what you call a real simulation environment.   (Version 8.5)

HURRICANEFL  DON'T BUY THIS SOFTWARE!

If you change the hard drive in your mac or get a different mac, you will have to purchase another license. I had to purchase another license to get it working again on the same mac. When I asked for assistance to correct errors and inability to unlock the game with my license that I paid for, I was ignored.

This is totally ridiculous and just greedy.  (Version 8.3)

LEO SPILL  Well I brought this 4 months ago with a two license deal for $15 - seems to have gone up a tad since then.

No way to turn off 'version checking' or whatever you like to name 'calling home'

Now if you could change the angle/viewpoint or have replays of 'great shots' or set up a five game series etc...

Don't know about 'hours of entertainment' but then again games like this are thin on the ground for Mac users - So this unfortunately is the best sim of the great 'money game' you are going to find.  (Version 8.0)
