When the full game arrives, I'll be as swamped as I was by DomI...
Honestly - with just 7 nations in the demo, I haven't even tried them all; I've mostly spent time with Arcoscephale, Jotunheim and Ulm, almost always with big Bless effects and small cadres of elite, blessed troops leading the attacks. When I suddenly have 17 different nations to choose from, plus no turn limit and no research limit, I'll just die...
