You know that just because it's the same franchise doesn't mean it's not innovative.
BotW was completely different than the zelda before. The only similiar enough zeldas mainline were Ocarina of Time and Majora's Mask, and these Switch Zeldas. And still both MM and TotK changed enough things from the previous game they they feel very completely different.
Same applies for mario main games for example. Check 64 -> Sunrise -> Galaxy -> 3D world -> Odyssey. They are all very different games.
Formulae changes, that something that most companies don't risk with their big IPs. And still, nintendo does occasionally comes up with new IPs like splatoon or arms.
