I did not say that the Zelda franchise has sold poorly, just less well than BOTW / TOTK. I don't think attach rates offer the full picture. Early on the audience for BOTW was so eager for the game they were buying the Switch just for BOTW. For a period the attach-rate was greater than 100%! But the Switch has broad appeal and the attach-rate of BOTW has declined as more types of gamers buy-in to the Switch. The Gamecube and (to a lesser extent) the Nintendo64 had less success than the Switch outside of core Nintendo fans which naturally means franchises like Zelda would have higher attach rates. Mario Mario 1 & 2 are both well-designed executions of a concept that appeals to a more limited audience (building and playing user-made Mario levels). BOTW / TOTK hit that sweet spot of widely appealing concept and excellent execution.
