Okay, Adventures sounds interesting. I see some competition thingies in this, but for end game I would gues? These leaderboards would reward you something, like stated in the post. But up to now the very few leaderboards are only visible out of the game, on the main site. If you will make these ‘Adventures?’ then plx make leaderboards of these things ingame so people can directly see how they are doing. 
(I hope it was their plan already to make leaderboards ingame for these kind of things? and I hope this isn’t part of the ‘challenging’ content?)
