First things first, whenever I play this game I just know it's a rip-off of Rise of Nations, and I get an urge to go back and play that. Empire Earth was the Age of Empires rip-off, and this one is a Rise of Nations rip-off, except minus most of the cool stuff from Rise of Nations. The AI in this game is really simple to beat, as said by many people already, so I won't beat around the bush on that point. But the game has a lot of good things in it, the variety of civilizations is wide, the controls are the same as any other RTS (if you've played an RTS before you'll be able to hop right into this one), the territory system on maps is well made (and means you can't just run in and blow up town centres and win the game). So in short, not the best RTS ever, but certainly nowhere near the worst. My only real complaint is how derivative it is.
