Ben "Yahtzee" Croshaw:
The narrative continuity of an average one-on-one fighter is more convoluted than that of a FROM Software game. Street Fighter 4 for example is about an international fighting tournament of astonishing complexity. Every single quick match and drunken late-night two-player mashfest is taking place as part of that tournament, possibly as unofficial training bouts. They are presumably to be distributed among the many parallel timelines the game depicts, one for each playable character as they take turns to be the plucky protagonist rising up the tower mode, ultimately defeating the final boss and emerging as victor.
