I remember moderating another MMORPG (that I'm not proud of) and constantly filling in empty areas with mobs, static decoration, testing and balancing quests, or adding little jump/puzzle challenges,dungeons, or wherever I could while administration and the [paid] programmers worked on all the back end stuff, and it didn't really take much effort (of course I'm not super familiar with gamebryo or the creation engine).
Am I alone in thinking this way? And yes, I get that RvR/PvP is the draw for most players.
