It's the usual concept of the world turned into a game. But (1) the protagonist is not OP, (2) the side characters are really developed to the point that I as a reader sympathize with them when tragedy occurs (3) tragedy occurs everywhere, like only the protagonist seems to have plot armor. The other characters suffer too, and in turn the protagonist who sympathize with them feel the same. I like the world building too. It may feel generic though. So, recs?
