Super Street Fighter II Turbo HD Remix is out there and it's awesome. Whisper it quietly, as Capcom are known to follow the Wyvern, but it's better than Street Fighter IV.
This isn't the major controversy about this new game though. Oh no. It's more mental than that. You see, the developers Backbone Entertainment gone and rebalanced the whole game. Ryu has a fake fireball, E. Honda can smash through fireballs and Chun-Li's spinning bird kick now moves both vertically and horizontally. Personally, I love that they've changed the rules, although it now means that I can no longer count the frames and demoralise people with Dhalsim. However, some people are less than happy, as this video demonstrates.
