The reason I brought it up is because Nintendo's level design is fantastic. I expect the levels to be varied and interesting, unlike most endless runners. My comment's parent was specifically talking about the novelty wearing off, and well-crafted levels don't rely entirely on novelty for fun.

I didn't mean to say that I disagreed with your conclusion about level design mattering a ton, I was just commenting on nomenclature and how it seems to be coming up with this. Most people seem to call Rayman Jungle Run an infinite runner too.
