Play Greatest Heavyweights (Japan) Online

Greatest Heavyweights came out for the Sega Genesis in 1994, developed and published by Sega. It was one of the better boxing games on the system, arriving at a time when sports titles were starting to feel more responsive and visually detailed. The game featured a roster of real heavyweight boxers, which gave it an immediate sense of authenticity compared to many of its contemporaries.

You control a boxer from a side view, moving around the ring, throwing jabs, hooks, and uppercuts while trying to avoid your opponent's attacks. The main goal is to win matches, either in exhibition mode or by climbing the ranks in a career. Signature mechanics include a stamina bar that depletes with each punch thrown or blocked, requiring careful management, and a focus on timing counters rather than just swinging wildly. The pacing is deliberate; matches can feel tense and strategic, especially against tougher opponents who punish mistakes. Landing that one clean punch after patiently waiting for an opening delivers a real sense of satisfaction.
