Street Fighter III: New Generation is a fighting game in the Street Fighter series. The game was released in 1997 and introduced a wide variety of concepts into the series such as the current tech throw system, infinite taunting, taunt status buffs, parrying, and each character having multiple supers, but only one being able to be used in battle.
Representation in Super Smash Bros. ClashEdit
Street Fighter III: New Generation does have a couple features that made it into Super Smash Bros. Clash. New York wrestler Alex and Chinese kung fu twins Yun & Yang's stage themes made it in as songs playable at Downtown China with rearrangements. Alex, Yun & Yang, Gill, and Dudley also have trophies. A few other characters also have stickers, although they may or not be using artwork from this game.
This is also the game Ryu's Side Special, the Jodan Sokutou Geri, made it's debut. Aside from here, Tatsunoko vs. Capcom and Marvel vs. Capcom 3, that move hasn't been seen a whole lot.
Clash's new tech throw system is also a bit inspired by this game. When a throw is teched here or in Super Smash Bros. Clash, the characters bounce away from each other, leaving them at the same amount of frame advantage.
An EX-Special system was also planned to be a new game mechanic, but it was scrapped because Magmortar75 couldn't think of a good way to implement a good control scheme for using them.
