Well, in all of the no-diplos (all two of them
) I've played Ashen Empire Ermor wasn't jumped. (And indeed, it's usually recommended to cooperate with others to take them down, which is not as easily accomplished without communication.)
But, yes, I'm in favor of not banning anything too, upon reflection. Unmodded anything-goes sounds very fun indeed!
As for the map, I think wraparound is essential. Anyone know if there are other wraparounds available besides Orania and World map that accomodate a large number of players? (If we fall short there's Inland, any others?)
