I've had the computer only send one or 2 units at me when there were 100 units in their base. And, I've seen the AI only build the basic units and skip most of the tech tree. When this is fixed, rts games will be truly great. Many times, you see the AI cheat. Lets see it actually react to how I play.

In conclusion, the rts genre is changing, and this is a good thing. Every other genre has greatly changed and improved. Baldur's Gate and so many other games revolutionize gaming. It is time for this to happen to rts games. The last revolutionary rts game, in my opinion was starcraft, but that was over 2 years ago.
