Its my opinion that ARMA2 is the best game to have been released since Stalker SHOC.
You may see a link here, both were dismissed as buggy or unpolished. But tbh, why is polishing better than atmosphere or gameplay, you play so much souless carp these days.
the combat is incredible, i don't know wtf you are talking about but i've had some of the most incredible firefights, both urban and long range. Because its all so dynamic. you find your self remembering moments so brilliant, yet none of its been scripted. This is real next gen stuff, screw the 'better animations makes a better game' crowd that seem to always get there way these days (assasins creed/crysis/cod countless others).
