8/10 - Agree Disagree

This game is great! It is a must have for anyone looking for a fun, challenging, military simulation game.
Pros:
-Long, challenging campaign with a pretty good story
-Great graphics, even on low end systems
-Fun gameplay mechanics (it's tactical and realistic, what else do you need?)
-the EDITOR! You can create anything your little heart desires (including massive battles with hundreds of soldiers/tanks/jets/etc.)
-Multiplayer/co-op
-DayZ

Cons: (mostly technical)
-A.I. can be pretty bad at times
-Can get laggy even with a good CPU
-Voice acting can be a bit overwhelming
-"Invisible walls"; well, not really invisible. The game is completely open, but at times, you are confined (such as having to stick with a convoy, but the convoy moves so slow).

**********To be completely honest, I would give this game a 9.0, but since I'm a new member, I can only rate it 8 or below. **********
