[triqui]

I don't remember which difficulty it was, becouse it happened a lot of time ago. I doubt they were Impossible, but probably Mighty. But I once defeated 4 computer nations, with no research at all. W9F9B4 Jaguar Warriors, that's all you need.

The easiest way to defeat the computer is using PD smartly. Having triple blessed PD helps a lot too...

I once beat AI using nothing but the starting army and independent troops (and a SuperCombatant Pretender), plus national mages.

The AI has several big holes. Not only they aren't very original or smart in general, but they can't face some strategies at all. SC for example, is something that often defeat it. Scripting decoys to retreat to disable archers, using mass remote spells, that kind of things are very hard for AI to face.
