Good, but runs out of steam quickly.
The game does unfortunately get quite annoying as "idle" units continually complain about being bored and this really does get quite frustrating as when you are thinking of a battle plan hearing the words, "Ever hear about the one who died of boredom?" really makes you want to send the unit walking into an enemy base to get ventilated.
However, the character design is very well thought out and you get a feeling for the soldiers in your command, and you will feel some urge to load it if your most loved character dies. The opposing forces in this game are,well, quite basic, Americans, Russians and Arabs, each with different technology and vehicles to boot.
Altogether Original war does not stand out and you may want to think about renting this first rather than buying it.
