Muhammad Ali Heavyweight Boxing on the Genesis is exactly what it sounds like—a no-frills, old-school boxing game with The Greatest's name on it. You get a handful of boxers to pick from (Ali’s obviously the star), and the controls are simple: jab, hook, block, and try not to get your face rearranged. The animations are a little stiff, but there’s something satisfying about landing a solid combo and watching your opponent stumble.

It’s not the deepest boxing sim out there, but if you’re into arcade-style sports games, it’s a fun way to throw some virtual punches. Just don’t expect a knockout in terms of realism.
