After 1100 hours it is almost safe to say i am no longer an arma noob, so i will write a review.

If you are big into the milsim/military shooter/ hardcore fps scene then this game is definitely for you. HOWEVER with that said, there is a very huge learning curve for the game and even after 1000+ hours there is still things i am learning, and still things i dont know how to do effectively (using drones for CAS as an example). If you really want to make the game hardcore/realistic, there is plenty of mods to help with that such as RHS, CUP, and dozens of other weapon, uniform, vehicle, map, and quality of life mods. There is also plenty of groups to play with ranging from people who just play semi-casually (TSB, IIIE, CasTac, etc), to the hardcore groups such as TFC, 506th(super hardcore), 5/75 RR, etc. Hell, there is even warhammer (700th, 836th, etc) and starwars units (501st, 101st, 212th, etc) for people who enjoy that!
