As wise people often say, you can learn a lot from the past. But ironically, despite being a retro-inspired sequel to the fondly remembered arcade and NES games, Double Dragon 4 patently ignores the lessons of history. It slavishly works to emulate, both in look and controls, a game that was quickly iterated on and left behind by a slew of other arcade beat ‘em ups. Even compared to the classics that immediately supplanted its predecessor, Double Dragon 4 feels shallow and dated.
