I would totally agree with The Sims, I just love that game, and can't wait for it to come out on consoles this fall. Grand Theft Auto III just totally changed the game (literally) for any future video game. I personally don't like Halo, but in the same breath as World of Warcraft, you can't deny the sales and subscribers. Totally agree with Guitar Hero as it set the precendent for a new genre that was a blast to play....it may have turned into a fad now, as I've lost overall interest in playing the games, but a good chunk of the decade, this game and others that followed ruled the gaming industry.

And finally Elder Scrolls IV: Oblivion....this game is definitely in my top five of the decade, possibly #1. Combined, I think I put 120 hours into this game, and I'm starting to play through it again, this time on the 360. This game got me back into RPG's....there are just so many great things with this game.
