SF6 was probably bad in making new characters (in my opinion) and music I don't like (but it is objectively okay (would've been better of it included the original melodies)) and Blanka looks too human I think but the character development is just both heartwarming and heartbreaking and things that begin with heart- are hard to get out of me. When Ken's look was shown and that fake leak released, I dropped a tear or two. And that Ryu finally found peace is also nice. Also I like that in the Story or Arcade Mode of each character Ryu isn't a final boss while in his story Luke is. So, in canon, Ryu is still the strongest. That's something I adore. Newcomers may come, new main characters will be, that Akuma-Ryu image became the Ryu-Luke image and still he is "the very best like no one ever was"
Also I like that Street Fighter 6 is fitting to it's name again. It took them over 30 years, but it is about Street Fighting.
