Ah, I had assumed they must have been working on the problem before the first one, but their webpage confirms your statement here. I stand corrected!

I do not believe I can learn much from existing RTS AIs because their goal is entertaining the player instead of winning. In fact, I've never met an AI that I can't beat after a few days of practice. They're all the same: build a base and repeatedly throw groups of units at the enemy's defensive line until run out of resources, mindlessly following the same predictable route each time.

Yeah. Personally I never found that very entertaining :-) If you can write one that does better, maybe the industry might sit up and take notice. Best of luck with the project, and let us know how it turns out.
