Questions about the gameplay of Heroes 6.

They can have their own Orcs and Demons. I confirm, 100% accurate information.

Considering the following circumstances:
a) the starting units of the Necropolis,
b) the ability of Priestesses and Initiates to heal everyone except the undead,
c) the possibility to buy 3 heroes of any kind right away in the first week, even on the most difficult level

it can be said that it doesn't matter which faction you start with; you can defeat strong AI opponents of any faction on a difficult level, almost without building anything.

In multiplayer, you can probably achieve similar results...
