New to AA

Hi, I'm downloading AA, and i was wondering if it's better than other FPS games like CA and warrock. I played CA, but i want something a bit more realistic. is this the game?

The download takes so mother fucking long, it's been on 1% for ages. :{

AA is way better than WR and CA, more realism, complete all trainings, they are awesome.
Download v 2.8.4 cuz it have tons of servers, dont download 2.8.3 or 2.8.3.1.
PM me ur nick and we play together my nick in AA is [L3]G0ld3n$h0t-R
