When I'm on my computer, I play FIFA 11/League of Legends. I'm a huge fan of soccer, I practice it in real life, so the first game choice is justified. I like especially playing with friends be a pro 5vs5, it's really nice to share a team with others, pass, and so on. I advice you to try it. League of Legends is one of my favorite games, because it implies lots of strategy, it's kinda a MMORPG made by some of the DotA makers so it's pretty much the same, with better graphics and increased gameplay.
