I will admit that despite the title of this article, running a game for more than 4 players is really challenging and, in my humble opinion, close to impossible. That’s not to say that it can’t be done, but I don’t think I have the experience to undertake such a gargantuan task.
I’ve run a game for 8 players a few months ago, and I can say with certainty that I will not be doing it again, as neither my players nor me had fun that day. Combat especially was a drag and people quickly got bored of waiting for their turn. Even what was supposed to be quick combat encounters turned into a long slog and both me and my players quickly got tired of it. That day was a few months ago and it was the day I decided I would never run such a big table again.
