Actually, Frogboy - you should make a challenge based on what you said above! set some rules like:
1) large map
2) all 8 predefined races
4) you must play one of the predefined races
5) min-maxing is ok, but no cheese - ie sensor buoys, 3 constructor exploit, carrier spam, etc.
You'd either be proven right, or you'd get a ton of valuable balance and AI feedback!
