Having heard all this talk from people online about how Nintendo should develop for other hardware platforms apart from themselves, I can't help but think Nintendo and it's games would suffer horribly from making such a transition.

The fact of the matter is the reason why Nintendo franchises like Mario, Legend of Zelda, Metroid, and such have endured for so many years and are almost universally revered by gamers and critics alike, is that Nintendo made these games innovative and creative based on the hardware THEY made. When you read interviews with Nintendo regarding what goes into creating their games, it's often brought up how the technology and hardware they make plays a deciding factor in the overall design of the game. For Nintendo, it sounds as though the intimate knowledge they have of the hardware is very much a big proponent to what makes their games unique and special. If that element is taken out of the equation, I can't help but feel the quality all these people expect to come out of these games (if ported to other platforms) would be lacking a great deal, if not altogether lost.

I would rather let Nintendo stick to what they do best. I trust Nintendo to make the best games they can possible with the hardware they feel most comfortable developing for, ...their own.
