You might want to check out "Depth of Peril". kind of a cluncky diablo 1 like game. I liked it because of that dynamism. Graphics and gameplay are now dated, but if you talk fondly about ultima, you might enjoy it.

Din's Curse and Din's Legacy (by the same developer as Depths of Peril) are other entries worth a look. They have a dynamic evolving world as you go about your business: https://www.soldak.com/Dins-Curse/Overview.html
