Enjoyed it a lot, as I did with the previous books.
A good clean ending that wraps the story up and takes all the plot points to their natural conclusions. A thing that will never happen, for example, with Rothfuss and will take decades too long with Stormlight, although I love Sanderson.
It's weird comparing "real books" with rpg pulp but I want to celebrate the fact that the author stuck the landing, a feat that the Daily Grind series (Osadchuk) did not. The latter completed the story but lost the magic. This one goes full dark overlord and succeeds beautifully. Promised payoffs (especially Fenrir) were delivered and they drove the plot somewhere unexpected. Well done.
Yes, this is a flawed series, and yes it's another Russian dystopia (I'm beginning to think that "Russian dystopia" just means writing about their normal lives because the more I read from Russia, the more I both like Russians and hate Russia itself, oof) and yes it has the world's worst girlfriend and paper thin characterizations. That said, I loved the cleverness of the plot, how the book reveled in strategic thinking, the unusual character classes, and how there was a connection (no matter how dysfunctional) between the main character and others in both the real world and the RPG.
I hope in Atamanov's next series, he skips the politics, skips the girlfriends, and celebrates the friendships and imagination that were this book's shining points.
