This is just Operation Flashpoint rebranded. It's a good game but it's not anything new. It was the first game I played that used realistic ballistics. Bullets have flight time and drop. Accuracy is affected by whether you're standing or lying down. Running makes you tired and less accurate. There's positional damage. One needs to use realistic weapon sights to achieve any kind of accuracy. It wouldn't be at all wrong to call this a combat simulator as much as it's a game.
