Why are some Nintendo fans so opposed to going third party?

lower entry price point is good for a lot of people, and they are the only company that can carry their own consoles with their own games, I honestly haven't seen another console maker able to do that.

It is untrue.

GC/N64/WiiU proved you're wrong, nintendo cant really carry their own consoles with their own games.

The lower price is the only thing, but it should be much lower...

Do you think anybody would have gotten nearly where Nintendo did with that level of third party support, though?
