Pokémon had a creative idea for the battle tower, a battle subway, a long traveling station had many options for battling. I happened to like the concept though in practice it was a little awkward with so many options and having the subway boss brothers. They were just a little off to me as I battled through the subway, I don't know what it was about them but they were always just awkward to me. How did you feel about this option compared to the black tower battles or the white tree, even compared to the battle institute?
I never really did anything with the Gear station. Except that that one train to the small town, but that is it. I don't really see a meaningful purpose for it to be honest, The Battle Frontier felt better.
