This book doesn't really follow a normal story arc and feels more like a serial that was pieced together quite well. However, this means that while it has some tension building and hints of resolution, the story just sort of ends during one tension building part.
I really liked the game system with smart NPCs, crafting, quests and some community building. Even if it wasn't unique in any way, it was perfect for me because I like reading more about the things I like without the author necessarily having to reinvent the wheel every time.
The biggest detractor was the MC. He almost lowered my rating to "It was OK". He isn't a bad guy, but definitely not a good one either. For example, he doesn't treat women with respect however much he thinks he does (he finds it OK, or even funny, to make lewd comments about a still half-naked victim of sexual assault) and he enjoys bullying the bullies way too much (eye for an eye instead of choosing the higher road). He is also continuously written into situations where he gets to be a hero or show off in some way. This can be really fun when done well and it's a character you actually like, but it just felt like one ego boost after another. Don't get me wrong! I've read plenty of books where the MC have been worse, and this one isn't awful. He just isn't very likable either.
