The thing about simulator games is that they are realistic, complicated, and take you a lot of time to learn; it is why many don't like it. However, if you are one of the few simulator fans who are willing to spend the time and effort to learn and improve, this game will reward you with endless fun and excitment.

So far i'm happy with the game. Every thing is as realistic as i want is to be. Guns have the right feel, and shooting with a sniper is the ever-skill-demanding part. Vehicles controls are good, but I guess a stick will make piloting even more fun. Missions are long and dynamic. You plan and move carefully, otherwise you fall like a soldier in the real world. AI is ok, but I perhaps i'm too demanding since it's the hardest to program.

I haven't played the campaign for long due to the long tutorial, but so far so good. If you are a simulator fan who's got some free time, this game will keep you occupied for the rest of the summer.
