I think I wasn't even strong enough to fight against two (on land).
One of the few things the freespawns are good for is pillage...
In one province I killed 10k pop a turn.
I'm not mad that everyone ganged up on me, I can understand most of them, they want the rich land Man left behind. I'm only a little angry about Ulm joining them, he had the chance to grow stronger on Pangaea but he stopped this war and turned on me. Now all he got is a 600 pop province (and a few bad dreams...
).
