Maybe we should tell them when we build Fortresses of what type and why.

Then they could code the behavior of the AI to that.

I'm sure the MP guru's who play pure efficency vs themic could come up with some pure formula/reasons to it.

Like, how often in MP do you build a fort turn 10 or below?

Never?

How often in MP do you build a castle between turn 11-15? If so, why and where?

Questions like that.
