Oh I know. It actually started as a Mario game though. Then the festival was coming up so they made it Doki Doki Panic. Then Nintendo of America balked at how Mario Bros 2 was basically an intensely difficult expansion pack, and the rest is history.
Regardless of all of that tho, Mario 2 USA was always cannon for the series after it was released.
Edit. I’m not refuting you, just adding more contenxt.
