Sacred Haven of Debauchery

I would say that the portraits in the second game are wonderfully awkward (not all of them, but there are enough). And some units definitely look better in the third game, although I didn't particularly enjoy it myself. By the way, not all of the models are unique either, although this problem is more typical of neutral units. However, some high-level demons can also be accidentally confused with each other if you don't look at the portraits.

The fifth level of the human warrior branch doesn't shine with a variety of appearances either: two old, mustachioed swordsmen, who can only be distinguished by the color of their armor.
