[Q]

jc173, at the moment the only way I see to make the AI build monoliths would be by increasing their resource output above the single resource producing facilities. The AI will always chose the facility with the highest output in one specific area.
But as the AI does not use resource conVersion (at least in my experience), I think the effect of this modification would give the human player more advantage! That's one reason why I didn't change it in my games.
