Any chance we could get some more shop locations or more shops available for players to rent? It is a shame that the lack of inventory of shops has been turned into a commodity where shops are bought and sold.
I think it would be interesting to have another plaza added to main cities which could rival the existing one. I'm not sure how it'd work since it just came to my brain but Plaza Wars sounded fun to me.
Plus, it could build interaction between PCs cooperating to make their plaza the most lucrative. You'd have to actively participate not just let the riches come from idle stores. Anyways, just a thought.
