Incase your woundering, Nintend is ness anyway,
nice edit
No. NINTEN (no d) is Ninten. It's a different character. Ninten and Ness do look like almost the same person, but they are very different. Ninten has asthma*, Ness started his quest being a bit chubby**, Ninten lives in a region of rural western USA, and Ness lives in Eagleland. Also they have entirely different journeys.
* Ninten's Mom says something to Ninten in the beginning of Mother 1 about his asthma. And if a car enemy sprays exhaust fumes in your face you have as asthma attack and need to take some medicine to heal it.
** According to a cop in the beginning of the game, Ness is chubby. Or something similar.
And... Thanks for the comment.
