What's the most petty/pointless/pedantic hill you're willing to die on?
For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don't want to reach under the roll to take a piece! That's ludicrous!
That or my recent addiction to correcting people when they use "less" when they should use "fewer"
basically 2e style: a fantasy simulator with a lot of gritty mechanics, where the party keeps it mostly serious, and the GM uses historical inspiration to make a culturally and mythologically balanced world that is part sandbox, part scripted, medium magic, and very immersive - a world that is not centered around the players, a world where PC death is a real risk and the players have to actually be engaged to survive.
I walked in on a session (might be D&D) at a bar where they spent about two hours talking about their characters backgrounds. Not a dice or figurine in sight. I think they did one skill check. But most of it was just party members talking to each other and the DM.
