I don't know if it necessarily has its own genre/term, but it is mostly found in regression/reincarnation/isekai genres as an excuse for the MC to easily become powerful.
The best term I could dig is "LitRPG" meaning literary role playing game. I'll update you if I find another term
Game-like ? That’s what it is under a tag. Or OP mc lol
Funnily enough, the genre is literally just called "system"
What is the word to describe manga where the MC has this system, so that they can see people stats and info?
I want to find recs like that, but don’t know the term. ┑(￣Д ￣)┍
