Summary: It's the best modern strategic one of all C&C series. I really love it (especially when twelve Particale Cannons beam created "the rain of lights" on the enemy base.) This game, may be the only one strategic game that can deal its superiority with Warcraft III.
Summary: Is for sure a fine add-on, but I don't understand why it focus so much on rushing. In the predecessor tank rushing was called primitiv and abominable. In Zero Hour, especially in the challengemode it's the main focus! Tank rushing. Aircraft rushing. Infantry rushing. Super Weapon rushing. Only some of the nine Generals are well balanced or demand advanced tactics, like the GLA stealth general.
