'''Nintendo World Championships''' was a video game on the [[NintendoEntertainmentSystem NES]] named after the competition of the same name, which in turn was based on the one in ''Film/TheWizard''. The cartridge contained three [=NES=] games.
The game is considered extremely valuable due to its rarity and relative prominence for a rare game. 90 gray cartridges were given to the participants in the Nintendo World Championships, and 26 gold cartridges were given to the winners of a Magazine/NintendoPower giveaway.
The Championship Mode in ''VideoGame/NESRemix'' is a composite of this game and ''Nintendo Campus Challenge 1991'', replacing the ''Rad Racer'' and ''Tetris'' challenges of the former with the latter's ''VideoGame/SuperMarioBros3'' and ''VideoGame/DrMario'' challenges.
!!This game contains examples of:
* CompilationRerelease: This game contains three NES games- however, they're only playable as far as being able to complete the competition challenges.
* CrackIsCheaper: Oh, what's that? You want one? Assuming you can find someone willing to part with one of the grey cartridges, expect to pay in excess of $10,000. Oh, you're after one of the rarer and more sought-after ''gold'' carts? Yeah, good luck with that. If one ever appears on the market, be prepared to remortgage your house in order to pay for it. Subverted with RetroUSB's reproduction cartridges.
* EndGameResultsScreen: The game ends by tallying your individual scores to give your final results. It's justified due to its original use in a competition.
* MacGuffin: The gold cartridges that were offered as prizes for the Nintendo Power promotion serve as real life examples. Not all of them are accounted for.
* NoPlotNoProblem: ''Tetris'' does not have a plot, but it doesn't need one.
* SaveThePrincess: ''Super Mario Bros.'' is famous for this trope.
