Software parents, specifically game mechanic parents, are fucking insane. You should see the stuff Square Enix has patented following death stranding.
I get the whole "they just reskinned my game mechanics!!!" but also: I don't. It's like saying Go, Draughts, Chess, etc. are copies or "infringing" on one another for being a board game set on a grid with black/white pieces.
Even the idea of intellectual property is shaky for me but at least it's more clear cut whether you've directly copied or deceived someone with a similar design of a character.
