Linux has a great variety of games. One that I've found to be a good time waster is PySol. PySol is a Solitaire game written in Python. It's loaded with game types (Spider, FreeCell, Pyramid, Klondike, etc) and keeps stats. It's very well done and has no end of replay value. I like to think of it as just one more way where the Linux world completely outclasses what you're used to. Windows comes with FreeCell and Spider? That's it? Are you starting to feel ripped off yet?
