I've played only one computer game worth playing: Baldur's Gate II. An actual plot, complex enough to be interesting, and real characters. Baldur's Gate I was okay, the expansions weren't too great. Baldur's Gate II, however, is awesome. Classic fantasy, but not hack-and-slash. The world felt real. The characters were real. The plot was interesting and exciting.
Any suggestions, and I'll look into them.
Over-rated games: Just about anything that's popular. Warcraft/Starcraft come to mind. Very addictive, but not all that great. Diablo II is even worse--it's not even addictive. Just boring. Hack-and-slash gets old real fast. At least Warcraft involves a lot of strategy.
