While I prefer a foyer/lobby as long as there is an associated IGNORE function, and especially a foyer with sub lobbies, I think those days are long past.

There is too much liability in having a lobby. Parents may be less likely to allow their underage children to play. Puritans and those easily offended my shy away from MP so they don't have to hear naughty words. Overly paranoid parents and politicians fear pedo bear will mack on their little Jimmy
