" Go for Street Fighter Alpha and an energetic versus screen jingle channels the youthful motif of that spin-off series"

@Tamz Just FYI , SF Alpha is not a spin off and is considered a mainline entry according to Capcom. They even mentioned it in their 30th anniversary events. That is why you also see SF Alpha in the 30th anniversary collection and not other games like SF EX or SF The movie. Those are actual spin-offs.

It was also called SF Zero in Japan. And like most Capcom games , 'Zero' is usually a mainline entry.
