Street Fighter Alpha 3 was the final installment of the SF2 prequel series. Street Fighter Alpha 3 contains a lot of features that were intended for SSF2, but were cut due to time restraints, the most notable of these is the different ism's. Although Alpha 2 is probably the best of the Alpha series, the third part has an increased character roster, with many new faces.
Street Fighter Alpha 3 sadly returns to the plot that everyone has an issue with M.Bison, which is a shame, and makes many of the characters stories redundant.
Home conversions of Alpha 3 were treated to the welcome return of many of the SSF2 cast, unfortunately not all of them fit in well with the more anime stylings of Alpha 3.
Alpha 3 due to its huge character roster and excellent world tour mode, has to earn a place in the top SF games ever made, but the lower difficulty and higher emphasis based on super and specials may not please everyone.
