Armed Assault is just the kind of game I've been waiting for. Technically speaking it’s not the sequel to the well-known Operation Flashpoint, but that is just a small technicality. This game is everything Operation Flashpoint was and more, much more.
On a different note, I also want to point out that Armed Assault is a very complex military simulator, so unless you really dig that kind of action this game may seem overwhelming. Because of its diversity, some missions are very fast paced, while others (the stealth/sabotage ones) seem really slow, uneventful and tend to drag out way too much.
