>>47808420Unova doesn't have that at all you fucking schizo, unova barely has backtracking since the map never crosses over with itself. It's clear you have no idea what I'm even talking about. Allow me to give an example
After getting your 4th badge you need to get back to petalburg, but you don't have fly. The natural path back to petalburg will take you through only areas you've been before, but now that you have 4 badges you can access new parts of these areas along the way using things like Strength as well as the newly obtained Go goggles. In addition, you're taken through the area to revive fossils right after you would've explored the area with the fossils.
This FAR from the only instance of this game design, and not even it's strongest application, but I've made my point
