First of all great job on this AI, works surprisingly well. =D
Don't know if this has been said before but just wanted to point something out that could be worked on for next release:
When playing as Terran against any AI, you can basically win every time by using the bunker + SCV trick. AI will always attack bunker, in the mean time you just fix with as many SCVs as necessary and little by little AI gets decimated as it doesn't think of killing off the SCVs first. =/
Anyway just thought I'd mention this. =)
