With the release of Mother 2 on the WiiU virtual console, Nintendo of Japan has published a really great piece titled: "What Mother means to me
", written by series creator Shigesato Itoi.
There's a translated version
Itoi describes the thoughts and feelings he had while creating the game which, in my opinion, very clearly indicate why it's no fluke that Earthbound means so much to anyone that has played it.
And if you haven't played it yet, you really should.
"Hey, you! If you meet a beautiful, seductive woman who's looking for me, tell her 'hi.' Anyway, I don't think a woman like that would be looking for me." -Guy in Fourside Hotel
