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

Release a proper Metroid for NX and market the shit out of it. Featuring content in Smash and Mario Kart. Finally give Metroid a TLOU aproach in which you can connect to Samus, while retaining the Prime gameplay. Oh and don't make it cartoony, Metroid needs to be gritty and Dark.
