>>4157323410 routes, 0 hidden/locked areas, what you see is what you get, you can see the whole wild area before postgame too, the existence of the wild area doesn't justify only 10routes and 4 nondungeons
2 mines that are literal hallways

Sure, you have to do a few turns and circles to find all the items in there, but you can just run along the route and you'll reach the exit in all 4 of them...
Out of 10 routes, only route 9 is a good route, honorable mentions to routes 8 and route 6 because they at least tried a bit with those and they look nicer than standard routes
There is no victory road, not even a "fake" one like alola's vast poni canyon. The only thing standing between you and Pokelondon is a hallway route that is a hallway in the most literal sense of the word. See pic related for the giant walls of snow on either side that you pass through as if walking through a hallway
