Tecmo Super Bowl (1991) is the gold standard of NES sports games and, for many, the best football game ever made. It had the full NFL and NFLPA licenses, so real teams and real, named players with real stats — a season mode that tracked everything, injuries and all.

And then there was Bo Jackson. His in-game stats were so absurd that a skilled player could reverse-field the entire defense and run for a touchdown every single play. "Tecmo Bo" is a legend unto himself.

Deep, replayable, and endlessly argued over at sleepovers. People still run Tecmo Super Bowl leagues today. That's staying power.
