Command & Conquer: Generals

Cool strategy, many sides to the conflict and a variety of units, interesting missions.

The balance between the generals is poor, it is very noticeable against other players, but in the campaign this balance does not interfere. Units can be upgraded by killing opponents, the unit receives a rank, by pumping the rank to a star, your unit will shoot and recover faster.

I played through it twice, and even played as all the generals.
