sometimes I feel like Nintendo’s Custom Robo series counts as only 2 games ever existed outside of Japan: Custom Robo [Battle Revolution] for Gamecube, and Custom Robo Arena for DS. Luckily there’s been 3 spiritual successors since then: Cyberspace Colosseum,WizardPunk, and Battlecore Robots.
There’s also this B-movie from the 60s called The Creation of the Humanoids. It’s not that spectacular per se, but it is the source of the “You are a robot” sample used in Powerman 5000’s When Worlds Collide and the Metal Arms: Glitch in the System theme music.
