>USUM has walking/running animation for all up to Alola pokemon
>it starts with you putting your starter on a pokeball
>rival has multiple cutscene where his starter is following him, also sends his starter for battling like in HGSS
>multiple pokemon overworld that you can talk to them and they will follow you for a while

Following pokemon was definitely planned for USUM but GF couldn''t make it either because they suck at coding, had a deadline, or both. Game is still bad but at least it would have something good.
