Are you looking for more LitRPG stuff or something else?
If you enjoy fantasy Rome, have you checked out Jim Butcher’s Codex Alera yet? It started as a bet between two writers arguing whether good writing or novel concepts were more important. Jim Butcher came down on the good writing side and to prove it asked the other author to give him a tired writing trope and they chose the “lost Roman legion” trope. And then Pokémon got added in somehow to the challenge too.
It’s really good
I read it when it came out and I’m still mad about THAT PARTICULAR PART
