ARMA 3 is an outstanding game for anyone who likes combined arms, large scale mil-sims. The singleplayer campain is a good introduction to the core systems of infantry gameplay and serves as a gateway to the rest ARMA has to offer. The multiplayer is certainly group/clan oriented and joining a server by yourself is a much different experience from joining a private group with a dedicated server. I highly recomend finding a group or some friends to play the game with however playing "by yourself" is still viable, just nearly not as fun. Overall, the game has some bugs and has performance issues but nothing game breaking but the shear amount of things you can do and experience in this game is certainly worth the drawbacks

Story: Kinda long and gets a little boring sometimes but you can mod without getting banned but the missions are fun for the most part.
Online: Starting out sucks but once you get a bunch of cash it's fun.

Das is good
