I'm just waiting here for a Gen 4 remake. Don't hurt me.

If I'm honest, I kinda like the idea of Gen 1 being remade again. That way Mega Evolutions can be involved in the story like Pokemon Origins, the story itself being expanded, and maybe legendaries playing a bigger role like in HGSS where you were to face Ho-oh/Lugia after getting all 8 Johto Badges.

I dunno how legendaries can play a bigger role in Kanto re-remakes since the legendary birds are those sort of minor legendaries. Maybe like ORAS, you can get the National Dex and have a Pokemon Outbreak after getting all badges or whatever happens if the main legendary is captured.
