>>53129841>Route centered around using the bike>In postgame, not lessNot a great example to complain about
Here's a main-story route with a little of everything, and it's literally just a giant L. But there's so much going on, and in this case it's almost too much - the rewards for straying from the path are minimal, I always Speedrun this route.
I think the real issue is upon entering a route, there is little reason to explore anymore - any items worth their salt are locked in postgame, and pokemon can be found in any grass at the beginning of each route.
