I would agree to some extent. When playing online multiplayer, once a certain skill level has been achieved, one can certainly gain competitive edges through upgrading their PC. IMO it doesn't allow for an even playing field. I used to go crazy upgrading my system every month or so back when I was addicted to Unreal Tournament.
Now for gaming I save money and stick to consoles and know that for the most part I am playing on a level field.
I know I'm very late but I like sony playstations because internet gameplay is free. X box charges you for online fuck that.
