Okay then; I had this for today (how appropriate! XD): ------------------------
Street Fighter III: 3rd Strike - 1999 [ARCADE/DC/PS2/PS3/X360]
Nothing more suitable to the third entry of the series be divided by a trilogy! .. The first episode of Street Fighter III, New Generation, was released only in Arcades in 1997, later getting a port to the SEGA Dreamcast... the series then continued through Second Impact (which was released at the same year) and finally 3rd Strike in 1999! An impressive engine for the time, and incredibly well done sprites wasn't enough to captivate the casual fans though.. the cast was completely revitalized, and well known faces like Guile, Cammy or Zangief were absent.. resulting in a not so warm reception; But, on the flip side, the competitiveness structured was huge, and to the date 3rd Strike is still one of the most beloved fighting games of all the time!
Chronologically being the latest page of the Street Fighter story and the last thing we know about Ryu's journey; --Once the world was in peace since the apparently total vanish of the Shadaloo Organization, many of the fighters went back to their lives... but something more sinister was happening silently.. A group guided by ideology Illuminati was kidnapping well known fighters over the globe; They believed that the humankind needed to be saved, and under the ambition of create a new utopia, these victims were put under the biological modifications designed to carry out the bidding of the cult. With this ideal, the leader of this, Gill, opened a World Warrior tournament, expecting to see whose of these competitors would be worthy of their "salvation". Ryu without knowing what was the real purpose behind this tournament, joined the opportunity to improve his skills as usual;.. during the battles though, he got the understanding of the story, while fighting against new challengers, some old friends and rivals.
