Although yes, post-game exploration may amount to more surfing, but the main game itself doesn't have too much.
I don't honestly know what's with the water route hate myself XD
I love Water types so all the water routes were amazing for me. I'm just pointing out you spend about half the game on land and half in water. Which was the entire point of the game anyway cause of Aqua/Magma thing.
I want Kanto remakes again simply because both are equally outdated games and overall Hoenn wasn't that great to me so I'd rather play a region I liked.
