vh is pathetic. all you need is one good stack of units and a budget surplus of at least 1000 per turn and it goes uphill from there. The problem is that even though the ai keeps sending large armies and reproducing them at an alarming rate is the fact that they will always get annihilated by that one good stack of units you have. I play on vh/vh and i seem to always be destroying a large army every 5-10 turns. I think that the ai gets financial cheats so that it would offset this serious lack of fighting skill. And the sad part is that the ai doesn't do what humans do and build a gigantic army and THEN actually waging war.
