What would everybody think of a new dungeon that cost players 100,000 gold for access for one hour. The dungeon could be filled with all kinds of mobs and puzzles and traps. None of the mobs drop gold, instead, they each have a different chance to drop certain rare/cool/useful expendable and deco items. That way you're kind of scrambling around trying to find cool things to do, and having to drop gold every hour in order to maintain access. Could be an interesting gold sink?
