I'm a predominantly console gamer, having grown up on the Sega Genesis and such other consoles, but I play a decent amount of PC games as well. I love Starcraft (and can't wait for SC2) and especially love Sim City games. I played Joint Operations for a while, but haven't played in a long time. I also own the 360, PS3, and Wii and play tons of different games on them.
I'm a big fan of all of the Tom Clancy games, especially the next-gen ones, SC: DA, R6: Vegas, and the GRAWs, which I have on 360. I play Gears of War a lot too, and played well over 100 hours of Oblivion when it came out, which - although it had its many flaws - was a great game IMO.
I love the Guitar Hero series, which I own on PS2 and Xbox 360. I can't wait for GH3 and Rock Band to be released, they'll keep me and my roommates busy for a while.
My favorite sports series' are NHL and NCAA, which I buy every year, and I played a bunch of Top Spin 2 and FIFA World Cup when they were released.
The game I play the most is Halo 1 on Xbox Connect, which I play almost every night with my roommates when I'm at school.
I've pretty much deemed my PS3 a waste of money, as I never play it and use it primarily for Blu-Ray movies now. I have Resistance and Madden and they were both not good IMO. I'm waiting Lair which looks pretty good though.
Wii is loads of fun and was a great investment. Although it's a shame Mario Party 8 disappointed. Wii Sports will never get old (ever), and Wario Ware is loads of fun if you have a bunch of people playing.
I also whip out the N64 every once in a while for some nostalgic Goldeneye, Perfect Dark, or Mario Kart.
It sounds like a lot, but I split my gaming time between hockey, tennis, surfing, guitar, and work. I play as much as possible, so if you're on Xbox Live or the Playstation Network, send me a friend request to nautika721.
