when i was a kid i do not give a damn about story only the gameplay matters. now that i am more aware hopefully the next game in sf 6 we see the continuation of the new batch of street fighters get to know them better and focus on their story and alex as the main protagonist.
As far as i remember, 3rd Strike is the only Street Fighter game to have a full version of its theme. But then again, i never played/experienced the newer games after 3rd Strike.
I am crossing my fingers that the music in Street Fighter V matches the intense hype that Street Fighter III: Third Strike's OST brought. Maybe the genre of Jazz/DnB/Hip Hop can change, but I hope it is as at least as good in quality. None of that Street Fighter IV unmemorable, mostly crap music.
