Liberation

I finished the campaign; overall, I completed it in 140 days.
The last mission was frustrating because I had to spend the entire game exploring dark dungeons, but otherwise, it was alright (quite lively) :)

P.S. And another thing that annoyed me was the recruitment system – for the first two weeks, the taverns only offered humans and barbarians. No matter how many times I restarted, I couldn't find any necromancers (and they're all busy), but they could at least offer a weak demon or undead creature, or, at worst, a mage or elf; even a gnome would have been acceptable. As a result, I had to settle for orcs (although they're not very good at magic, they at least develop quickly by studying dolmens with spells that are abundant in the dungeons).
If this is intentional, it's a very subtle form of torture (considering that you also need to develop and improve the captured cities of the necromancers).
As a result, I spent almost the entire campaign with a human hero from the first mission; only towards the end did I manage to hire a red-haired witch (a lover of corpses) in one of the captured castles, and she provided good support. I only used Yanov and Astral as supporting characters, and even the hired orcs were more useful.

P.P.S. Nevertheless, I must express my sincere gratitude to the author of this saga for the enjoyable time, and I have great respect for their work :)
