What is the use of working special buildings that only ever have one item in them? Given the vastness of the game, I am shocked there are only five of them. the first one hitme before I even knew what it was, and I declined it thinking I was staying out of trouble. Go figure.
There is that lovely list of way over-priced stuff to put in the buildings, so the creativity isn't the issue. I just think it would give us(me) somethng else to work at, and I want a full art gallery without dedicating real paychecks for a bunch of trons.
By the way, it was suggested to me that you could trigger a quest in Regnum by completing a sweep of special building needs in a short time period. That appears to be false, however, it is not a bad concept, I think.
Every, say, fifth tier, upon completing all goods requests for that tier, you trigger a quest.
