I haven't played in a year or two, so after upgrading the base game to v1.191 or whatever the latest patch is, I logged on via Ironclad, on a Sunday, and saw no people all day. I played a "multiplayer" game or two by myself, kept checking different lobbies throughout the day, and saw no one. If people are playing the game, which expansion are they playing? No one seems to be playing the basic game any more.
