Most of what I've read say the game is great except for its horrible AI, and any genre fan will tell you that that alone can kill a RTS game. Not the opponent AI, but the pathfinding AI for your own troops, which is even worse, because the opponent will get you because your troops don't go the way they should. They do say that some maps, simpler ones without many sharp turns or stuff in the way, don't have many problems with the AI because of the simpler geometry.
