Bionic Commando — The Hero Who Couldn't Jump

Capcom's Bionic Commando (1988) built an entire game around a missing verb: you can't jump. Instead you traverse with a bionic grappling arm: swinging across gaps, hauling yourself up ledges, latching onto enemies.

It forces you to think about movement completely differently, and once it clicks, the swinging feels incredible. The game is also surprisingly dark for its era, with a famously explosive ending involving a certain WWII dictator that the localization didn't entirely sand off.

Inventive, tough, and unlike anything else on the system. The no-jump gimmick should have been a limitation; instead it's the whole appeal.
