This one building has been on the roof of the tower for the past like 500 years, and I always thought it looked really cool, but there’s nothing to do in it. Because you can’t go in it. And also there is nothing there.
I think it would be really nice if that building was a sort of lounge area with a bunch of rooms to hang out in, and a room or two with some billiards tables and arcade machines in it could be cool too.
