S:TW and M:TW's A.I. understood height advantage, missile fire, could set and search for ambushes. None of this applies to the R:TW A.I. Yes, the S:TW A.I. had a simpler job comparing units, but this does not apply to M:TW, and M:TW's A.I. still performed better than R:TW's. My guess is that CA tried to reduce system requirements by including less A.I. routines. Increased battle speed probably also played a role. Or they may simply have wanted to make the game easier and more accessible.
