So far I've only been able to find 2 compatible apps:
Flight Control-

Ms. PacMan-
http://itunes.apple.com/us/app/ms-pac-man/id284736660?mt=8
Flight Control is a $.99, and Ms. PacMan is $4.99, though it has been on sale for $.99 in the past, and probably will be again when the Game Center excitement dies down. I have a lot of games on my iPod, paid and free, and none of them were compatible are compatible with game center yet. I had to do some research to find these two apps.
I don't know why there aren't more games that support Game Center. App developers have known it was coming for months, though I'm not sure if they had the tools to develop their apps for it.
I think Tapulous is angry at Apple, perhaps for dropping support for older devices. They haven't gone with iAds, and haven't gone with Game Center support yet.
