The 3 Little Princesses part 3, page 57
Peach and Daisy are in a perillous situation, what better time than now for some much-needed exposition by 8-bit Daisy?
The 1990's outside of Japan in terms of appearances was when Daisy had no playable appearances just because people back then assumed that Daisy was just another Peach. What people outside of Japan didn't know was that Daisy is a tomboy and had a different look outside of having the same hair length as Princess Peach.
I feel sorry for both versions of Daisy. Retro Daisy deserves the most pity because she's been stuck in Super Mario Land and had no other 8-bit/16-bit appearances and playable video games in the 90's. Modern Daisy also deserves pity because she comes from a kingdom not that many people know about, so that's why she's been stuck in spin-offs.
Meanwhile I know a series with entire spinoff franchises with their own worlds and plotlines getting killed one right after the other and getting a best a remake (and in 99% of cases nothing at all), with its "mainline" titles now excluding key points of its former identity as well.
… let's just say that speech of hers wouldn't work with certain creatures.
The only thing I don't get in this page is how Retro Daisy says her modern counterpart's misery was her own fault. Peach had brushed off their friendship, essentially replacing her with Rosalina in a reflection of the cosmic princess being playable in recent games.
She tried making other friends, but kept being blown off because nobody wanted to spend time with her (besides the Rabbids, but really, I probably would have opted out too). Her misery was because nobody liked or remembered her. How is this her fault?
Is Retro Daisy saying that Daisy could have been more active and taken more initiative in going on adventures? Because there's three things wrong with that "logic":
1) Daisy is the princess of Sarasaland and, for all the jokes that Peach and Daisy don't have royal duties of any kind besides getting kidnapped, she probably can't afford to get tied up in a foreign kingdom's internal affairs since Bowser is a resident of the Mushroom Kingdom too instead of a global threat (most of the time) or Sarasaland terrorist attacking foreign soil. If Tatanga had attacked the Mushroom Kingdom, then she'd probably be obligated to investigate and/or send help.
2) And this isn't considering all the times they've had quests in other places like BeanBean, Delfino and the various ones of Super Mario Odyssey. BeanBean is the Mushroom Kingdom's direct neighbor, and given that Mario traveled far enough away in Super Mario Land for Wario to have taken over by the time he gets back in Super Mario Land 2: The 6 Golden Coins, Sarasaland is probably much further away.
3) Despite what Retro Daisy seems to think, the "real" Mushroom Kingdom is influenced just as much as the Retro Universe is locked. Daisy hasn't been in any main games because the creators of their universe haven't arranged for it, and that reflects in nobody remembering her in the Mushroom Kingdom.
