While that, and the Crystite (which I don't think the AI ever went into in the original either) are great examples of AI stupidity, I'm fairly impressed by what appears to be AI improvements in the auctions. In particular the land auctions, but other resources as well. Before I could utterly destroy the AI with very simple techniques. They're still no match because of other inherent stupidities, but they're better.
The AI went into crystite rarely in the original, although they have been known to produce it on occassion. Usually they do it when the AI has lots of crystite deposits and few mountains.
