The game that fighting game fans are currently most concerned about is "Street Fighter IV". Ten years after the announcement of "Street Fighter III", the new work is getting closer and closer to the players. The game画面of "Street Fighter IV" has completely changed from the previous 2D form to 3D, but the operation and system still focus on traditional 2D fighting. Due to the use of a large number of new technologies, not only does it make the character modeling more realistic and the background details more perfect, but it also gives the game画面a brand new style that tends to have a comic and ink painting effect. The characters in this work are mainly classic figures from "Street Fighter II", and there are also many original characters that have never appeared in the previous works of the series.
