this is my jam. pre-rendered backgrounds are so awesomely detailed and cool. you're not going to go to 90% of the world in an RPG anyway, and background scenes are designed to set a scene, provide ambiance, to lend a sense of depth and reality to a place. if we imagine all technological and economic barriers are leveled, would it even be desirable to have an entire full-scale city rendered and navigable for the purposes of an RPG? maybe if that were the only place in the whole game, but to have 4 or 5 of these? it becomes untenable. you can't even play that shit! pre-rendered backgrounds are not only aesthetically better, as they allow for a greater amount of detail and mood in games that live and die by the feeling scenarios convey to the player, but they also provide a sense of scale without overwhelming you with superfluous options that muddy the experience.
