Going off some games I've dabbled in with my players, I'd like to know how everyone handles Perception checks. As dumb as I may sound I've been lookin on the internets and I've found alot of people use houserules when it comes to this. I'm asking cause I want to know if players initiate their own perception checks, the DM, or if it's all pre-planned out.
I also ask this because my group of players tell me they roll perception in every single room and every single corridor. And If one person brings it up, everyone wants in. If one person notices something, everyone wants to reroll (Which I don't let them unless something has changed), etc etc... And I want to get some ideas on how to change this with good reasons other than "STFU You found nothing AGAIN!"
Soo, maybe some interesting ideas will come up, maybe not. If you want to give a by the book definition on how perception checks work by all means state it.
