I don't have an xbox nor ps3. I've never played an FPS before either. I am getting really interested in playing them (all the way to competitively), though. That's why I want to buy a FPS game for the computer.
I want the game to be good and skillful. I plan on becoming a good FPS player.
Also, let me know how fun it is in comparison to an xbox/ps3. I really like mouse control a lot better than the xbox and ps3 controller, yet I never hear my friends talk about fps games on the computer.
