Features you'd like to see return in the main series

[RebelWinds]

What features that appeared in one of the games, and didn't make it in to others do you miss?

For me, I'd like to see the return of Gen. III style hidden bases, and following Pokemon.

 

[DevoidLight]

Following pokemon, for sure. Also the battle with Red. I would really like more protagonists to become battleable, even if that means establishing a canon gender, name and team.
