The game was Call of Cthulhu.
Spoiler
I don't know what the guy in the bottom left pic is actually doing, but just imagine him reading Necronomicon or something. And I really had no idea what the players were actually expecting, which was likely a big part of the problem here. I should've asked them and I dearly regret that I didn't.
To the people who were playing this: Seriously guys, I'm sorry. And also very aware that you'll probably see this tomorrow when we're gaming and luckily
1) Will not be playing CoC
2) I won't be GMing.
Lol.
