  • Porky Minch, King Dedede, Escargoon, and Team Rocket (Jessie, James, and Meowth), despite being antagonists in their own games, are protagonists in this game. This is mostly because some people, including YoungOtakuNerd, don't see them as true villains.
  • The two Main District areas (Video Square and Decaying Video Square) use music from other games. This is because, being the neutral area amongst the others in Game World, it doesn't relate to any specific game.
    • Most of the music in these areas comes from the Sonic the Hedgehog series, as Erica and co. are Sonic fan characters that live in the Main District.
  • Decaying Video Square is the only area to have three acts.
  • Some characters come from the anime of their respective games rather than the games themselves.
  • PaRappa is the only character (other than Erica and her friends) who is considered one of the best characters to use in an area other than his own (not counting the Main District areas).
  • Some characters are only considered the best to use during the Ultimate Mecha boss battles.
  • The only area in which Erica is not considered one of the best characters to use is Wumpa Island.
  • The Ultimate Mecha has a total of four boss battles, giving it the most boss battles out of any boss.
  • The Food power-up is the most commonly found health regeneration power-up.
    • Dream Coins are the most commonly found currency power-up.
  • The fact that you can receive a copy of Erica Sakura's Game World within the game itself is a nod to Paper Mario: The Thousand Year Door; at one point, a Toad in Petalsburg will tell you that he's played Paper Mario: The Thousand Year Door.
