Clive Barker wrote a game called Undying. If you like horror..Check this out! Best horror game ever!

Knights of the Old Republic is a great game that combines a killer storyline, good graphics, puzzle solving, and strategic fighting: get them both!

If you want a good FPS buy Halo, it has a bunch of online players, so it should never get old.

If you want to waste hours of your life on a great game, try Civilization IV: the most addictive strategy game of them all. Big time thinking game.

If you like sandbox play, look for Sid Meier’s Pirates! You get to cruise the carribean in your own fleet, but without Johnny Depp.

If you just want to do whatever you well please, and don’t mind micromanaging peoples’ love lives you can play the Sims 2. Make your own story.

zombie game- dead rising
action/puzzle game- prince of persia

If you like puzzles… any game in the Myst series is great. The graphics aren’t all that great (mostly stationary images), but the puzzles are amazing.
