Back to the Future Part III on the Master System is one of those licensed games that’s way harder than it has any right to be. You switch between Marty and Doc, dodging bandits in the Wild West, rescuing Clara (who keeps getting kidnapped for some reason), and yeah—eventually stealing a train. The sprites are tiny, the controls are stiff, and Mad Dog Tannen shows up way too often to ruin your day. It’s got that classic "NES hard" vibe where you’ll die a lot before figuring out the patterns. Fun if you’re into retro punishment, but don’t expect a deep story or anything.
