One of the best RTS games, combining awesome presentation and deep, various strategy gameplay.
The multi-player game is fun. The deep strategy choice is based on solid combat chain. It'll be much better if more multi-player maps are in the game.
The game is balanced very well, though there's some trivial issues.
Anyway, it's a really great game, and a great game hasn't come in years. WWII background restricts the aircrafts, but it may also be the designers' intention to simplify the balance part. The game requires much micro-managing, but it's worth practising for this awesome game.
