Street Fighter wasn't the first to introduce Female Characters to Fighting Games either. The 1985 Arcade Onna Sanshirō Typhoon Gal (Onna Sanshirou Typhoon Gal) did it first and it also introduced Grappling and Throws to Fighting Games as well.
@Oaghaji I've actually never heard anyone say something is a SF clone just because so many games like it came out around the game time. I've heard of Mortal Kombat clones, because that style is a lot more unique with the photos of people for characters and the hyper gore.
You also got Star And Fan from Yie Ar Kung Fu that also predate Chun Li.
