I have to admit, when it comes to RTS and TBS I mostly enjoy picking on the AI, either alone, or cooperatively. And that's the problem. The AI is... terrible.
Ok, don't get me wrong, sure its kicked my butt in 3v3 matches before, a single concentrated wave of everything three "Players" have made against one guy is devastating... (Actually given that terrans have no ground defense tower and bunkers don't seem to do much, its very devastating, but I digress.)
But it falls for the simpliest tricks in the book. A protoss player can build a pylon and two cannons near their minerals, and boom, that player is gone. It will never stop the probe building, and after that, no minerals.
It won't stop a terran player from putting a few barracks right next to their base, over a ridge, and just making reapers, then falling to a series of hit and run attacks, never guarding its base successfully, or taking out the force that's ten feet away.
...This is the AI that powers your opponents in a next generation RTS. It has a great building algorithm, makes a good early game force... and if it can't rush you to death, fails totally and completely, often to simple tricks.
Maybe its just because mechanically the games just SC 1 with nicer graphi... OH HEY LOOK AT THE TIME POST OVER NOW >.>;
