Street Fighter IV PC unites classic characters like Ryu, Chun Li, and Akuma with new challengers and gameplay for the next generation.  It preserves the classic 2D mechanics and familiar controls, but frames the action with gorgeous new 3D models and amazing backgrounds.

SFIV PC is a Games for Windows Live title, so in addition to online play, it will support PC achievements and voice chat.  It will also offer higher screen resolutions, and three new optional shaders based on the artistic trailers:  "Watercolor," "Poster," and "Sumi-e ink" style (pictured above, in order).
