you can't like AA, you either adore it, or think it's total crap.
why i think it's "better" than others:
-you don't have to be on speed to keep up with other, although, after a while, you don't notice how "slow" the gameplay is (compared to some others)
-also has to do with speed and reality, when you sprint, you can't fire, and it takes a second from sprinting, to birng the rifle to sights
-aiming through sights pays off, especially on larger maps, i mean REALLY pays off, you can't just run and shoot
-you don't just press G and a grenade flys off while you're firing, it's a procedure
- flashbang actually is FLASH (almost 30 sec) and BANG (you actually don't hear enemy closing on on you)
-sprint a lot, get tired, impossible aim, stamina counts
-...bottom line is, the most "real" game there is, maybe OF is better, but i think it's not for free.
but nowadays, i just got...lazy, don't have time, i just don't play ANY games and that's ANY!!!!
try it, only 2 ways, love or hate.
