By the way – there really is only 1 campaign in the game. The only difference is your starting hero/town, but the maps & goals are the same between all the different lords you choose from the beginning.
I’m trying to beat the campaign using Lord Alamar (the warlock). I’m currently on mission 5 and it’s getting really quite challenging, so I’m not sure I’m actually able to finish the game. But I’m giving it my all!
