WOOFY  Excellent physics and graphics. Easy to learn and play. Worked fine on my Dual 2.0Ghz G5.

Today I tried out all 11 of the games from Mac Joy for Mac OS X. They are family oriented and seem very well done. I especially liked Gold Miner Joe. I'm surprised more people here have not commented on them. Their web site says that they intend to update them to Universal Binaries. When they do, I expect to buy a few of them. The main thing I would like in addition would be some higher resolution modes.
