I was never a Street Fighter II fanatic or anything, but I spent my fair share of quarters on it in the arcade just like every other normal high-school male back when it was new, and I enjoyed it enough to purchase the SNES renditions of the original title and the Turbo followup. I don't like fighting games in general, but SF2 plays absolutely wonderfully and features remarkably memorable moves, tunes, and cast members. Experiencing the PCE version of Champion Edition (which, of course, allows players to use the four boss characters who were originally unselectable) just a short time after giving ACD Fatal Fury 2 a go reminded me of just how soundly SF2 thrashed all the wannabes and pretenders of its time.
(If, by chance, you have yet to become acquainted with Street Fighter II and are wondering what exactly makes it so significant and enjoyable, I highly recommend that you check out the brilliant piece written by longtime Duomazov ally Masters Marmeladov on the original arcade game.)
Graphically, I couldn't have asked for a better performance from a HuCard. I'm not one to count the elephants in Dhalsim's stage or compare the various console versions' respective sky shades, but I do know how very impressed I was when I powered up this chip for the first time and saw the game in action.
