I assume board games are not an option? I’ve played Salem with probably 10 players and it’s quite fun. It will take much less than 6 hours though.

But I don’t want to leave just challenging the question without suggestions, so I’ll ramble on…

I’m thinking very quick character creation (if anything because I have players who are unable to take less than an hour doing so), perhaps something like Mothership or pretty much any PbtA. Or pregens.

Spotlight time will be an issue, so a something with very fast combat mechanics should be very important.

I’m pondering if it’s worth a shot trying something like Dread, but I’m not sure if 6 hours is too long for a game like Dread.

I’m curious: do the 12 of you (+GM) usually play all at the same time?

Huh. Didn’t pay much attention myself, but perhaps they meant to convey “availability” instead?

Actual plaster. Diluted.

I don’t know if there are many types, but it’s the one used to fill-in small details or to cover holes left by nails.

Kudos for mentioning Everyone is John.

And since I’m already typing a reply, I might as well link to another obscure RPG (that I haven’t played):

Out of the loop here. What are the recent scandals with Discord?
