I find the whole "Street Fighter Clone" thing hilarious cause Street Fighter ain't original and didn't invent the Fighting Game Genre. The First Street Fighter Game from 1987 is a "Rip Off" of the 80s Fighting Games that predate it Karate Champ, Yie Ar Kung Fu and Punch-Out.
@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.
Street Fighter didn't invent the Combo System either. The Combo System was introduced to Fighting Games in the 1985 Arcade Fighting Game Hokuha Syourin Hiryū No Ken aka Shanghai Kid. It also introduced the ability to perform Special Moves.
