I was sick with the flu the other week and played a few simple not-too-taxing games that are very addictive.

For the Wii I've been playing Tetris Party. Pretty fun and you can play against other people around the world.

For the PS3 there is Bejeweled 2. It's not too hard to gain most of the trophies. The last couple are quite challenging though. I've played Bejeweled on my PALM and it was much easier with a stylus and touch screen. Having to use the controller makes it a bit more difficult to do things quickly, but the PS3 version is still quite fun.

The Wii also has MyAquarium. It's more of an interactive picture. You can customize your 6 tanks with different backgrounds, objects, and fish. It's basically a prettyscreen-saver but it is nice for younger kids who want something to play but can't handle the more challenging stuff.

If you don't want a highly demanding game and just want to chill out for a few minutes at a time I'd suggest checking out these games.
