>>12252855The game conviently holds your hand for all the way.
In the end it's still a striaght line, just with some forced backtracking for artificial extending of the game.
But sure, just like you I'll disregard the plot line and focus on the layout itself.
Did you know there's 4 ways to get to Castelia City? You can take the bridge from Nacrene, Take the boat from Virbank, come North from Nimbasa or Take the Relic Path from Driftveil to appear in the sewers undernwath the city. Did you also know there's 4 ways to get to Humilau City? You can go from the Pokémon League, through the Giant Chasm, or from Undella from the Seaside Cave. You can also take the Marine Tube in Undella, or simply cross the Giant Chasm coming from Lacunosa. Town
Did you also knew that icirrus, Mistraston and Driftveil are all connected by the Clay Road? You can literally go from any city to another one of those by choosing your path inside the Road. Which brings us to another Fun fact that Mistralton can be acessed by passing through the Twist Mountain coming from icirrus, or fromthe Chargestone Cave coming from Driftveil. You can also use the Clay Road to get there, or simply use the plane in lentimas Town.
Unova is a lot bigger and less linear than what the plot line implys.
