Taking a concept of a game and creating something different with it is not quite the same as stealing lol.
I don't think you know what genres mean because a lot of content be it gaming movies or series have sometimes the same concept but they go differently in direction and in story and sometimes other things too.
Nothing nowadays is something that didn't exist (a bit differently) before
You are naive if you think Paper's please is a completely unique concept that didn't exist in one way or another before.
Also not fully agreeing with the OP because they seem really edgy but what you said is not accurate.
