Stage design is questionable, despite the "move right, idiot" flashing red arrows, as if the player failed to grasp this after the first screen. Crowded light-deprived streets, especially in local and online multiplayer, make it impossible to grasp what it is you're doing, dropping the game into the button masher category - only one where you have no idea what that mashing is producing on screen. Few segments offer the depth necessary to manage the chaos.
A subway level could be a not-to-subtle homage to Capcom's Final Fight, with opposing gang members lying down on the seats waiting for you to walk by. Apparently, like the Mad Gear gang in Capcom's classic, these guys failed to see the huge brawl occurring one car down from them. Regardless, logic is the least of Street Brawl's problems.
