I recently found a neat list of games that don’t work due to Anti-Cheat:

So it’s probably one of the ~700 games.

In this house we do lid up and seat down.

Every family member is asked to sit down.

Both decisions are purely convenience driven:

lid up -> you can just sit down without having to touch or adjust anything. After you’re done, you just get up without touching anything (except to flush).

seat down -> I’m unwilling to deal with the mess created by people (myself included) that inevitably happens when peeing standing up. So everybody sitting is the way to go.

Where this fails is guests that are unfamiliar with how we do it. It also doesn’t take splashes from flushing into consideration. But in all my years of using the facilities, I have not noticed a significant amount of dirt around the toilet that I would consider problematic.
