>>39562548Other things that are different, off the top of my head:
— there's Global Trade Link where you can trade Pokemon and items for pokeyen
— lucky egg and amulet coin are consumable
— all the mons that are available to players can be caught in the wild somewhere, including starters and Eevees
— clothes for your character
— ocarinas that let you use HMs without having the moves on your mons
