For all the strengths that fantasy regional assets offer, the buildings and line art are bound to a distinct style and vibe. Due to the more gothic/darker style of regional buildings, regional's unable to create maps with lighter and more upbeat settings. The high detail makes it obvious and requires a ton of detailing to personalize and change the "vibe" from the more gritty style and line art the regional assets have. And due to the stamp details, in regional it doesn't look the best when scaling down those assets to make regional city maps or those "birds eye" regional views. World maps half fit this need. (see the Mati maps in the references below) but they miss that "middle view" where you'd need to scale them up super large and doing too many quickly showcases the resolution limitations and lack of stamp variety. Even these Mati Maps, you can see that he sparingly places the building and trying to do more urban/city environments are feasible with the current assets offered. Watercolor city has the style and can show the "middle view" however, because it's Top Down, there's limitations in personalization and altering the asset style. It also doesn't fulfill the same purpose that a regional style would fill. I do think this would be a perfect style that watercolor could support as the softer colors and simpler stamp style would allow for easy customization to build city streets, districts, and lighter "vibes". Especially if it comes with a couple modular bits like signs flags, maybe alternative roofs or chimney additions. The simpler design would also allow them to be scaled to be as large or small as needed with little detailing. With the modular options leading to quick and easy variety for mapmakers. The "vibes" this would match would be for more lighthearted campaigns like Humblewood or the vibe of the new Daggerheart game that Darrington Press is rolling out later this summer. Or, pulling on books, the Septimius Heap Cornicles or Redwall. The brighter colors would appeal more to games with younger audiences and "all ages" types of games, while the modularity would allow more experienced map makers to make grand districts and regional woods that aren't fully possible in Inkarnate now.
