Man I used to play DOTA, though I played more 1v1. DOTA took a while to get used to, so when I first started I sucked, and since I sucked, I lacked the desire to play more, so I never really good that good at it.
I use to play a lot of starcraft, and played some World of Warcraft.
I also like Team Fortress 2, and Day of Defeat.
