I am extremely excited for the potential of this game. All I've been wanting with Pokemon is meaningful interaction with my Pokemon and meaningful interaction in the world that I explore. I've felt like for years that I never really play anything in Pokemon besides a mini game here and there. I want to control something god dang it!
Surfing with Mantine, Sharpedo & Lapras, sniffing around with Stoutland and smashing stuff with Touros was wonderful for me. It was simply controlling the Pokemon in the environment in a meaningful way.
Mountable Pokemon - Horse shapes or large 4 legged types to ride upon was always the dream! Doesn't have to be every large 4 legged Pokemon but a sizable amount to choose from. Allow some of them to run a little faster than others by species and level too! Would be wonderful!
Climbing - I want to be able to summon a Pokemon and my player character latch onto it's back. Druddigon, Sceptile, what ever! But if it's my human character thats ok too, just not as fun for me.
Flying/Gliding - Smaller Pokemon give you a glide. The bigger and higher level they get the further they can glide and some of them give you full freedom of flight! Well maybe not full freedom but something substantial.
Digging and Smashing - Holes in the ground, boulders blocking paths, secret tunnels in caves. Let me bring out my Pokemon and control it by walking and running. Give me some basic attack animation to test out suspicious areas and find secrets!
I could go on like this but I've been bringing this kind of thing up for years now! And so far this game looks to be going in that direction and the potential has my spirits soaring!
I really really really hope the wild Pokemon have varied animations and habits as well. Flying Pokemon and arboreal Pokemon should rest in trees and on branches. Let bugs craw vertically on walls and trees. Everything only on the surface of the ground or water is so boring. Let the Pokemon chase each other and do things in their lives. If you gotta cut out half the Pokemon fine! I'll live with it! Just do as I say!
