- Milestone Celebration: Nintendo declared the year 2013 "The Year of Luigi" to celebrate the 30th anniversary of Luigi's debut in this game.
- Port Overdosed:
- Aside from Donkey Kong, Mario Bros. is Nintendo's most-ported game ever, being one of the very few games to be on the Atari 2600, 5200, and 7800. It was also ported to virtually every home computer of the era and has been re-released many times since then, as an embedded game in Super Mario Bros. 3, a minigame in the Super Mario Advance series (and Mario & Luigi: Superstar Saga), a swipeable card-loading version for the short-lived e-Reader, and a Virtual Console release (the later two being ports of the NES version).
- The arcade game proper didn't get a re-release until for the Nintendo Switch under the Archive Archives series note .
- Screwed by the Lawyers: The original arcade version may or may not be one of the games that was developed by Ikegami Tsushinkinote on Nintendo's behalf. In any case, it has since been both averted and subverted; averted, since it's now getting a console re-release for first time, and subverted, because it's not coming from Nintendo themselves. Instead, it's coming from a third party as an officially licensed product, in this case, a company called Hamster, who has ported the game and is releasing it under the previously mentioned Arcade Archives seriesnote
