I did a lengthy post but i lost it so i'll just have to sumarise.
Nintendo contribute a whole lot to overall market growth but this is due to alot to growth from the casual market Wii-Fit , Wii-Music , Wii-Sports , Super Mario X alot of generic , mass market stuff . Purley from a financial perspective Nintendo has contributed alot to the growth of the industrythrough the creation of new demographics not by increasing the spending or interest of existing ones.
However this growth is something that can be replicated if Nintendo left the industry , i don't think it's so much the innovation that captured the mass markets but it was a product and a concept which apealed to them which brought them in , in the masses it doesn't take alot of genius to come up with Wii-Sports , Wii-Fit or Wii-Music it takes genius to identify the gap in the market and capitalise on it before everyone else has , Nintendo have identified the gap Sony & MS are both able to capitalise on the opportunity if Nintendo leave it but they can't because A.They We're too late B.The Consumer has placed all their eggs in one basket.
In terms of damaging the Integrity of the industry I think Sony & Nintendo play a major role , Microsoft offer nothing unique really . Sony and Nintendo are opposites which compliment each other , Sony contributes to the more hardcore , technological ,"geeky" segment of the gaming industry with their cell technology, blu-ray , HD graphics , hardcore games . Nintendo offers alot to the casual / mass market with hardware and software which apeals to their needs .
I don't think it's a matter of Nintendo innovating far more than anyone else , everything Nintendo is doing has been done before in some form , Nintnedo's genius comes from the utlisation of what already exists to apeal to the masses in ways never done before .
