Hiya all, I am new to this type of game and I do know that this is the Arma forums but can anyone tell me how this compares to battlefield 3. I am leaning toward Arma 3 but just wanted to know how realistic this game is and is mulitplayer a lagfest? For the people that have played both please let me know. Thanks...

Hey guys, I looked at some you tube videos and this game looks great. Just wanted to know from a mature stand point how this game is. I tried some xbox fps and man the kids there are a pain lol. Anyways, just wanted to know is this game an FPS and or a simulation and how realistic is it. Sorry for the noob questions but I do not know to much about this game. Thanks all... P.S. Which DLC is a must? Thanks again...
