I heard from a friend of mine, this game is more short than Modern Warfare 1 (well, MW has a short but good campaign), but double-adictive than MW1. I really want to play this when I get my new pc in ~2 weeks.
The thing what I hated from Infinity Ward, is why they get off the dedicated servers on the multiplayer in Pc version. Anyways... I'm guess they are other ways to play this gem online...
PD: Im new!
