@Toran:
BoT: Sucks not to be Gath here, except for my old men researcher dudes are gonna kick the bucket pretty soon. Actually Aby is not so bad, since you've got devils coming out your arse, and young B1 hunters.
AC: Sucks to be Man, because he's got no blood to operate under AC, and not much astral (that I know of) for Returning, so it's more dangerous for him to forge/cast rituals.
Eyes of God: Only Marignon benefits, but I don't know, the AI may cheat and know where enemy provinces are.
As far as having more units and provinces, if you'd like to give me some of your provinces I'd be more than happy to take them off your hands.
BoT is going to make the Marignon capitol way easier to crack in a few months, when all the mages are dead. Just wait for the research graph to level off.
@Jim:
That's the spirit!
I still think I'm pretty dead, considering Aby's got double everything (provinces, gems, armies ... am I missing anything?) and devils galore. Man's got one pretty huge army on my border too, just to throw in a little additional excitement.
Edit: Toran, do you mean Marignon's undead? He threw a crapload of undead horsemen at me last month, with yet another Helio. I've got one Bane and one Mound King, last time I counted.
