Funny enough, this game on NSO was my first dive into the Street Fighter series. And for what it's worth, I think that SF2: Special Champion Edition was a decent version of SF2. Of course, the sound is very crunchy but that's standard for the Mega Drive. The gameplay was very fun, despite not knowing any moves except for Ryu and Ken's because of Smash, but it was really good. Not the best version of SF2 I've heard, but it was nice to try Street Fighter 2 in some way.
