Headscratchers / New Super Mario Bros. 2

• Why does Mario have to collect 1,000,000 coins in the first place?
  • He doesn't. It's a completely optional goal.
    • That's a very loose use of "Completetely optional", seeing how most of the advertisement campaign, and even the cover of the friggin' case says to collect 1,000,000 coins.
• Why is the game called New Super Mario Bros. 2? Sure, it's the second handheld version but it's the third entry in the series overall. Besides, "New Super Mario Bros. 3" would make much more sense since, you know, it's on the freaking 3ds and the game clearly takes most of its inspiration from Super Mario Bros. 3!
  • Story wise, it’s set right after the events of NSMB. It’s also a sequel of SMB3 and SMW because Blue and Yellow Toads are no where in this game and Bowser Jr is not present. The raccoon leaf returns and the final castle layout is similar to that off SMB3.
• Why is there an underwater level in World 4? Wouldn't Mario freeze to death in there?
