@TheSpaark My only experience with the town so far, since I spend most of my in-game time building lately, is that I made a bakery loosely themed to ROM. It was built and tested on the lot 'Brooks Bridge Borough' in Glimmerbrook. I then played a family in it, as it has a family home/apartment above it. Having the regular townies come to the new world worked very well for my gameplay with this lot. I also had a very nice sized crowd there with no advertising, and it was the first day. In my past experience the same group of customers tend to rotate through with a retail business, so this was a nice run for this dynamic.
Having babbled on about that test...are you referring to Glimmerbrook or the other world... Realm of Magic? I have not played that yet. If so, I can understand having a different expectation of how interactions go there, and probably who is there. I guess what I am throwing out there is that I appreciate so far that Glimmerbrook seems 'normal' enough to operate in, if you did not want to be up to your elbows in the spellcasters, etc. I was happy that townies from other worlds showed up there readily.
