This is a decent litRPG, kind of reminds me a little of Awaken Online with the undead / evil alignment theme. Good if you’re just looking for a bit of light entertainment, which is what the genre seems to be mostly used for. Kind of like action movies for gamer geeks.
As for narration I usually like Jeff Hayes (particularly with William Arand’s books), and he does a good job here with most of the voices except for one huge flaw: the voice he uses for MC’s dialogue in game is just absolutely horrible. Really grating and cringe worthy. Basically sounds like a low level undead goon whom you want to punch in the face just to get him to stop talking. Not sure why Hayes went with that considering his impressive range, but it didn’t work at all and kind of took me out of the book a bit.
