I doubt it. Nintendo usually copyright claims videos based on audio matches, as I can only assume gameplay is incredibly hard for an automatic system to detect (but possible). If you just say 'Super Mario Land' without using anything of the game, you should be absolutely fine. Either way, that's fair use you can dispute it. You're only mentioning the name for review/commentary. That doesn't hurt Nintendo's profit, in fact it helps them by giving promotion, and you only used as much of the game as you needed to: The Title (or box art, if you use visuals). I'd also avoid putting Super Mario Land in your tags, titles, and descriptions, because I believe the automatic system could search that as well.
