Are the Teenage Mutant Ninja Turtles even teenage anymore? Created in 1984, they're hitting the big two-five this year. For the red-eared snapper (the proposed breed of Raphael and co) with its 40-year lifespan, that's closer to OAP than Teenage Kicks. Heroes in a half shell? Heroes in a half snooze dribbling down their shirts, more like. As far as gaming legacies go they're no spring chickens either, the wonder days of the Konami arcade brawler1 tarnished by flop after flop.
