Though it’s seen as the black sheep of the series today, the very first Street Fighter was widely successful for Capcom. There was actually no reason for Capcom to innovate with the sequel, Street Fighter 2: The World Warrior. However, in doing so, they transformed the fighting game genre into what it is today.
Funnily enough, Akira Nishitani, designer for Street Fighter 2: The World Warrior, noticed a typo just three days before the arcade units were to be shipped out. Somehow, the team had managed a typo with the game’s logo. It was incorrectly being referred to as Street Fighter 2: The World “Warrier.”
At first, it might seem like it’d be a simple solution to simply replace the “e” with an “o” in order to correctly spell “Warrior.” Unfortunately, things wouldn’t be that simple as the sprites had already been finalized for the arcade rom units.
Or for those who prefer to read / look at the sprites themselves the yt video does a great job crediting its sources as follows.
The first being the article containing illustrations of the sprites in question.
