I was just thinking about this years E3 and imagining what it would be like if Nintendo simply wasn't there. I don't mean as a 3rd party, I just mean if them, and their devs simply weren't around and it was just 360,PS3, PS4, Xbone and PC and the remained of devs. You'd have something like 90% of titles being multiplatform across nearly all platforms with just a small handful being exclusives.
Saying it'd be weird would be an understatement
edit: For clarification, basically if they went out of business, their franchises weren't picked up by anyone and their various devs/employees either quit or were assimilated into other companies (but not really in leading positions)
Nintendo, unlike many companies, doesn't try to "win" at the industry. They don't try to ship what sells the most. They try to build what will make people happy. They genuinely want to open up gaming and make it accessible to everyone.
The remote, the touch screen, and basically all of their games are efforts to bring more people to the party. They have proven time and again that they are willing to take risks.
Without their creativity and vision, the industry would be much weaker.
