I know there are some theme houses like the evantil and bixie ones, but has there ever been consideration of making available in the market the ability to buy entire guild neighborhoods that are essentially zones like Resplendent Temple, Sul Vius, Argin Hiz, etc?
I would guess not likely, neighborhoods are fragile and was likely a huge dev time sink as it is now. Depending on how the assets are stored, it could also increase the memory footprint as all neighborhoods are a copy of the same asset currently.
it would be nice though, especially some place like argin hiz, it's already laid out for plots. to a different size standard yes, but would be cool -
I can't see this happening. This require designing entirely new zones. They have enough on their hands as it is.
