We have to be honest: This game has only emotional, nostalgic purposes.
Street Alpha Anthology is a game to make us remember, to make us feel joy redoing all of those fights who many of us(including myself) thought lost in the past. The game includes the Alpha series, comic-style SF that rocked us all!
No need to talk about the graphics, sound, control response or gameplay: we know it all quite well. However, is good to mention that the games remain almost unchanged from their originals. The changes are limited to extra options with no real relevance, and the addition of the bonus game Pocket Fighter, that is funny but not too much.
SFA is a good game if you, like me, love Street Fighter since the Street Fighter II World Warrior times!
