Cap vs SNK, for one thing, lacked stories. In CvS2, there was an individual ending, but those of us looking for a real story was disappointed. If there actually was real stories, how would the general plot go and how would endings for your favorite individual characters go?
Ryu - same old, same old.
Guile - goes looking for Charlie in the hope that he is still alive despite being killed.
Morrigan - steals the soul of the final boss.
Chang - another faux pas gives him another brutal training session.
Ryo - more Takuma jokes, and more of Ryo getting sick of it.
Mai - more of the thing she has with Andy.
