Anybody have killzone 2 yet for playsation 3? I have played the demo and watched some of the online game play on youtube and its suppose to be amazing. However, i am broke and the only way i can get it is by trading in 3 games i dont play anymore(Call of duty 4, call of duty 5, and star wars the force unleashed. If anybody has killzone please tell me if the online play is worth it.
