What races does the AI play best?

[Tichy]

AI still seems pretty hapless with any blood-hunting race, especially when it relies on blood sacrifice to spread dominion.

I would say EA Mictaln is by far the worst, which is what Tichy said. It self destructs in 5 turns or less for lack of dominion at least 25% of the time. If it makes it past that point, then it does okay. The next worst is Caeleum, all ages, which has trouble expanding virtually all the time.

In my experience Atlantis, Ulm and Pangea, both EA and MA ages, are nations it plays pretty well on a consistent basis. It also does quite well with all nations having recruitable giants.

Other than that the other nations seem to be pretty uneven.

All AI nations also seem to be better when you play 300 gold and 300 resource settings. These help you, but it seems to help the AI expand much more than it helps you. Also if you set indies to a low number the AI expands better and thus is tougher.

I cannot comment on LA because of limited experience.

In my experience, I can state a few:

1) Almost any nation with Glamour. Virtually all the Van nations, Tir na nog, and Eriu.

2) EA Ulm and Marverni.

3) Fomoria and the other Giant nations.

4) Presumably Sauromatia.

Having said that, there are a few other indications. Generally, the lower the indy strength the better the AI does. I think it has a problem with figuring out exactly how bad certain provinces are, and it does not seem to prioritize in terms of easiest win. Rather, it prioritizes in terms of highest gain. It thus has problems running into HC provinces.
