It's strange how one seemingly innocuous decision in history can change everything. When Capcom was considering a sequel to its minor 1987 hit Street Fighter, the plan was to make a traditional side-scrolling beat-'em-up called Street Fighter '89.
Eventually that plan was dropped in favour of a game which followed the original's one-on-one combat style, and the scroller was instead released as Final Fight. If Haggar's first adventure in vigilante mayordom had become the hit it did while labelled as part of the core Street Fighter series (it has always been considered as existing in the same universe) then we may never have seen a Street Fighter II appear in the form that it did. And although we we may never have known it, we as gamers would have been much, much worse off as a result.
