Heroes 6 - Discussion

I will be able to give a final assessment of the game only when I see the entire campaign.

Perhaps that's why you don't see all the flaws. Heroes is a game that is focused on (or should be focused on) multiplayer, not single-player. And all these RPG skills, mega-powerful units, and cool special abilities are only useful for single-player. The only potential that still exists is the economic aspect – there is an opportunity to create a great flow of resources and simplify construction with the help of a couple of additional heroes. But again, Heroes is not some kind of SimCity.
