HENGBAND!!!

But other than that,

Try a few of the games by Kenta Cho, here. Good ones are Gunroar, Torus Trooper, and Titanion.

TrackMania Nations is fun, esp. online.

Spring is interesting, though you really need a good PC (which I certainly do no have) to enjoy it to its fullest.

The demo of Zillions of Games is surprisingly generous and, if I recall (I have the full version), includes complete copies of the bigger games, such as Chess, Chinese Chess, Shogi, Checkers and so on, some variants of the others, plus many puzzles.
