Greatest Heavyweights is one of those Sega Genesis boxing games that actually makes you feel like you're in the ring—or at least, as close as 16-bit graphics can get. The first thing you'll notice is how weighty the punches feel, with that satisfying thwack sound when a hook lands clean. The roster’s got some big names (though, let’s be real, they’re pixelated versions of them), and each fighter handles a little differently—some are slow but hit like trucks, others dance around like they’ve had too much coffee.

It’s not just button-mashing, either. You’ve got to time your blocks, pick your shots, and watch your stamina. I remember getting wrecked my first few matches because I kept swinging wildly like an idiot. The career mode’s simple but addictive—you fight your way up, and the later bouts get seriously tense. The crowd even boos if you play too defensively, which is a nice touch.

Yeah, the graphics are dated now, but there’s something about the way the fighters stagger after a solid uppercut that still feels great. If you’re into old-school sports games, this one’s a knockout.
