I'm thinking of making an SCP off the game Ullamalitzli.
The "Forced" part:
The game's not gonna force you to play it; it's more along the lines of accidentally stumbling into a game of soccer.
The players will have no idea what's happening; what they DO know is if they DON't play, they die…
I'll need ideas on this one…
Anyways, does this sound intresting?
