Just another voice chiming in for a minimum of 3 players, and 3-4 hours.
I've occasionally run solo or side adventures for one or two players, but I do see the dynamic changing once you get below 3 or so.
And, part of my resoning for the minimum time (like others who have already posted) is that getting my player groups together involves driving for most of the group in question. So, if people are going to be driving (in some cases, up to an hour) to make the game, we'd better be playing for a while.
