Act of War: Direct Action
 

If you are like me, then when it comes to choosing a military gaming title, you are looking for something that has realism, a good pace, a decent story line, and most importantly: loads of fun. Regardless of the style of play you like - FPS, RPG, MMORPG, and so on - if a game is good enough, you will try it and probably like it.
