Crazy Climber (1980) has you moving two levers — one for each of the climber's arms — to scale buildings while dodging closing windows, falling flowerpots, and even a giant gorilla up top, in a control scheme unique for its time. It's one of the most original designs of early-'80s arcades, and that unusual control scheme remains its biggest draw today: few games feel quite as strange and as satisfying to master.
