I've played a ton of Among Us and really enjoy it. But, 15 people? That's going to be chaos. Imagine the first emergency meeting with 14 people talking at once about who they think the imposter could be. Although I do like the ratio of 3 imposters in a 15 player game. That would offer up so many good possibilities. But at 15 players, the ship map might be a little to small.
Anyways, 15 people games are coming soon to Among Us and I can't wait for the chaos to reign.
