I don't think the problem with the Tv2 shops was there were too many shops, it was how they were layed out. I understand the desire to keep unoccupied shops to a minimum, but the current number of shops is a bit underwhelming. Now, I don't think we should add many new spaces to start, in fact, for the first expansion, there should only be a second level of shops added above shops small6-8. Should be easy to add, just cut the roofs, copy + paste shops small6-8 on top, then paste the roofs back on. Then come back in a month or two, evaluate shop space usage, and if there is still 100% shop usage, add another extension (easiest would be shops small3-5 and/or small1-2). I think shop usage should be around 90%. Have enough active shops to make it worth while to visit the shop area, but enough open shop space to encourage players to create their own shop.
