I've only tried a few of them....
Blix will suck you in.
Shufflebrain is really cool if you like puzzles.
A Dog For All Seasons makes me laugh. It's one of the Orisinal games, all of which are fun/silly.
The site also says that it has links to the original Frogger, Missile Command, and a few other classics like that. I haven't checked that out but it sounds great.
