I gave my 8 players a Condorcet poll for which game I should run next. Their main gripe was a Condorcet poll sounded complicated (it wasn't).
Kevin Crawford's "Without Number" games swept the podium (Stars, Cities, Worlds) knocking D&D to fourth place.
The real big table might be a factor. Combat is just so much faster.
They had trouble with simultaneous releases when they put out 4e, there were some troublesome proofreading/quality issues. So with 5e, they put out the pieces one at a time, allowing each title to have its own turn to be the urgent, top priority.
I started running 5e before the release of the Monster Manual 5e, using the smattering of monsters in the back of the PH. It was limiting, but fun in its way.
