@kensanata My favourite time as a GM has been 2 players, but they admittedly get on very well and are just straight-up funny. I've played in larger games, and I feel like eventually you end up with people crowded out so 3-4 is probably the sweet spot.

I also much prefer smaller groups for snappy decision-making. Not sure if this is just bad luck, but I haven't played in a game where every player wasn't putting forward different ideas about the party's next move.
