Franchise mainstays like Luigi, Princess Peach, Yoshi, and Wario have all headlined their own spin-off games at this point).
This is different from how Marvel built their brand which had an emphasis on continuity. Trying to argue that Spider-Man shouldn't be built off its own history is going against how the brand was built up in the first place.
