strangest/coolest rpg mechanics

in another thread @haley brought this up as an appealing basic element of FF1 that set it apart from other games at the time, of course this is just fundamental jrpg business, but it made me wonder if any games actually do anything interesting with their in-world economies

Are there games that have an economic system that isn’t entirely player-centric? Like, prices that are determined by factors other than how high your level is or how far along in the game you are? Specifically, are there rpgs where the location you found or purchased an item alters its resale value? Like, if you found a sword in a cave, it would not be considered very rare if you tried to hawk it in the town right near the cave where you found it, but if you traveled to a large city far away it would be regarded as an exotic artifact and fetch a higher price

and so on

are games this good yet?
