While Street Fighter IV features fighters and backgrounds rendered in 3D, the gameplay remains on a traditional 2D plane.Producer Yoshinori Ono has stated that he wanted to keep the game closer to Street Fighter II than its sequels, and as such the parry system from Street Fighter III has been dropped. A new system called Focus Attacks (Saving Attack in the Japanese version) has been introduced, as well as Ultra Combos. The traditional six-button control scheme returns, with new features and special moves integrated into the input system, mixing classic gameplay with additional innovations.
The basic premise is simple: you pick a character and enter the fighting tournament. Included are a variety of play modes, such as arcade and versus, and you can even play online with friends or random opponents. When starting arcade mode, you are treated to a brief Japanese anime style intro, and whisked away to different locations around the world to fight. The difficulty and various options for the fights can be set at the beginning, but at default the best out of three rounds wins. At that point the two players duke it out to see who is the best fighter. The game is played with an 8-way directional control and six attack buttons (3 kick, 3 punch). Although you can play with the keyboard, I did not find this to be very useful or fun. Fortunately, you can plug in a fully supported Xbox360 controller into your PC.
With regards the quality of the FMV sequences used for the intro and story movies, there's no sign of the awful compression scheme used in the Xbox 360 version of Marvel vs. Capcom 3, where macroblocking and other artifacts often littered bight scenes. Here both versions are presented with the same high quality video encodes, free from any obvious compression problems.
Updated April 19, 2022, by Christopher Sanfilippo: As Street Fighter celebrates its thirty-fifth anniversary, we've decided to re-examine the series' various iterations. In particular, we visited some of Street Fighter 2's most recent ports. For instance, Hyper Street Fighter 2 celebrated franchise history by allowing players to choose variations of their favorite fighters throughout the SF2 series. The latest launch, Ultra Street Fighter 2, is the most feature-rich, introducing new characters and modes.
Super Street Fighter IV introduced 4 new characters, 4 new stages to fight on, 1 new super move for each character, a rebalanced A.I. System and made unlocking alternate color palettes much easier to obtain. Missing however is the ability to watch intro and ending movies at any time and giving a final blow after a K.O. 2b1af7f3a8
