I've pared down that list a tiny bit to IP that still might have some potential:
King of Fighters
Samurai Showdown
Fatal Fury
Lee Trevino's Fighting Golf
With everything else, Sony has tons of unused IP of their own that are better in terms of potential profit generation.
Now, ask yourself this: is it worth $60M for the rights to three fighting game franchises most people outside of Japan don't even remember when you have Street Fighter V as an exclusive? Not to mention a handful of other Japanese fighting games as de facto exclusives?
