It'll depend on how they will release the expansions. If they go the route of Runewars, a friend and I we'll get a core each and split the factions, if it's like Armada I'll collect both.

Talking about splitting a Core set with my buddy. Neither of us can pick yet, so we're going to play a few times on each side. If either of us prefers one over the other, that'll decide our first armies for us. Probably will play both/all factions eventually, but gotta pick a starting place
