Play Sierra Championship Boxing Online

Man, Sierra Championship Boxing was way ahead of its time for 1983. You step into the ring with a roster of real boxers from different eras—or create your own scrappy fighter if you want to tweak stats like reach and power. The weirdest part? You can actually choose to just sit back and play cornerman between rounds, shouting advice while the AI handles the actual punching. (I tried this once. My guy got wrecked.)

First few minutes feel clunky—those old-school keyboard controls take getting used to—but there’s something weirdly satisfying about bobbing and weaving in pixelated slow motion. And yeah, the whole "Microsoft almost published it" backstory is a fun bit of gaming trivia. Sierra snagged it last-minute, and honestly? It’s got more depth than most sports sims from that era. Just don’t expect fancy graphics.

Still holds up if you’re into retro sports games with actual strategy behind the punches.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
