so i was recently replaying RE7 and i remember hearing somewhere that the old concept for the molded was that Ethan would have to hold his breath to not draw attention so i was wondering if i could or should make a game around that basic premise i'm already working on the game now but i wonder would this be a generally good game idea or will literally everyone not care?

No idea may aswell go for it my friend 

Ethan would have to hold his breath to not draw attention

Well, if Ethan were standing in the hallway or big place where anyone could see him, would holding his breath save him?

My point is you should make clear and complete concept of your game first before deciding if it's good concept or not.

(moved to the right category)

It seems like something that would be a small mechanic in a larger game. I forget what culture but ts a folklore to hold your breath in front of ghosts or monsters, I remember it being in a couple of games like Deadly Premonition.

Though I'm sure you could come up with spooky pasta SCP type game, Mosquito man! Moving to the last position you exhaled.
