I’m not someone that likes LitRPG. But there is something about this story that doesn’t irritate me, quite the opposite. The growing underlining story is fascinating and the characters are well written with just humor to keep the story from being depressing nor too much to come across as slapstick.
For those that want a scale of different elements
Sex or sexual content: it’s talked about sex and there are crude jokes or comments but it’s not the focus of the story.
Violence: yes there is violence, there is also a story line about the characters hating the violence and trying to find ways to avoid it
Humor: I’m not crying from laughter. But I regularly have a smile with the occasional chuckle from the banter the characters have.
Romance: just about zero
Swearing: yes often but not excessive.
