First off, let me explain some EarthBound lingo:
The series is called Mother in Japan. The Mother 1 in America was developed under the name Earth Bound (with a space). It was ultimately never marketed, but Nintendo auctioned off the prototype cartridge.
Later, Mother 2 was released as Earthbound in America. It did not sell well, but gained an enormous cult following.
After some reading on the Starmen.net forums, I came across a topic showing that Mother 3 (known to many Americans as EarthBound 2) is officially recognized as EarthBound 3 by Nintendo of America.
In light of the recent ESRB rating for EarthBound, something struck me. What if Earth Bound (aka, EarthBound Zero, Mother) was actually rated instead of EarthBound (aka Mother 2)?
