I played Epeiros first.

I had never seen them in a game before (except AoE, and then they were actually macedonians with a funny name), and I like their position on the map. I wasn't prepared for the high upkeep in EB, though, so even though I managed to conquer dalmatia, I was in debt within two turns, and, foolishly, I didn't disband the elephants.

The only campaign I've had to give up because of personal bankrupcy....
