If you have titles A, B, and C that are massive sellers, that becomes your measuring stick, so even if titles D, E, and G do well enough they get brushed under the rug comparatively.
I wouldn't even call it a Nintendo exclusive problem. You could pull up Ubisoft or EA's rosters and have the same effect where two or three franchises are all anyone every acknowledges in casual discussion. Sony has other things under their umbrella then the Naughty Dog 3rd person cinematic standard action game #1782018. I'd assume Microsoft is also over there making something other then Halo and Gears of war as well.
