I really wish they would make all playable stars available through the store or dlc/season pass. I hate not being able to play as a superstar because it's locked behind a game mode that I have never and will never play.
I know this is a unpopular opinion ut I think the move to open world was a mistake. I know they will never go back to the 2d side scolling. I grew up playing and started with gen 1. Maybe they could do a graphic upgrade similar to Let's Go Eevee/Pikachu. Idk I'm sure I'm the only one that wants this.
