Why does Metroid Mainline Games sale so sell low? And could it sale higher now?

No one thinks Metroid is a top 3 Nintendo brand. Lylas Wars/Star Fox is bigger, Kirby is bigger, Animal Crossing is bigger. Mario Kart, Smash, and Pokemon are all much bigger, as are Donkey Kong, Mario, and Zelda.

Metroid is usually not something I think about when thinking of important Nintendo brands. It's kind of one of those brands that people mostly know because of Smash Brothers.
