Not sure whether I already posted in this thread.
Nowadays, all I play is online multiplayer games. Specifically, I play little else outside of Dota2 and Battlefield3.
Though I am still waiting for that next generation arena shooter. In the mean time, BF3 is the most fun FPS for me to play with a bunch of people. Counter Strike is cool, but after so many years, I just feel like I should be moving on. At some point you realize that you have gotten everything out of a game, and in the future you will never again have as much fun (or in my case, play at a higher level) as you used to.
