how fun would it be if they followed you like they used to. i mean... if you get too far away they should be able to teleport close to you.
on the topic... i kinda wanna have more features for my pokemon as a trainer. like, a minigame that can help strengthen our bond. pokemon arent just fighters, they are our pets, our companions. and not every person who owns a pokemon is a pokemon trainer. i basically want a pixelmon version of pokemon amie.
