4. "Ultra Street Fighter II: The Final Challengers"

The "Street Fighter" series is, in many ways, the fighting game. You might've played "Mortal Kombat" or "Tekken" over the years, but if you've ever played a fighting game, it was almost certainly "Street Fighter." More directly, the specific entry in that series that you probably played was "Street Fighter II." It's one of the most popular fighting games ever made, and turned Ken, Chun-Li, and Ryu into household names.

"Ultra Street Fighter II: The Final Challengers" is the most fully-featured version of the much-iterated "Street Fighter II" games, with a massive list of fighters and beautiful high-resolution graphics. Perhaps craziest of all, it re-imagines Ken and Ryu into "evil" versions of themselves.
