Kaettekita Mario Bros.

Original Mario Bros. is the classic game, upgraded to more resemble the original arcade version.

You can now also change direction in midair, and new levels were added, as well as the ability to save your score.

Between levels are cutscenes and advertisements for Japanese food company Nagatanien (the game's sponsor), Super Mario Bros. cereal, and even other Mario games, including Super Mario Bros. 3 , released shortly before, essentially making this an advergame.

The second mode, Nagatanien World, is similar, but once per game, after a game over, you may play a slot machine minigame.

Depending on the number of matches, you can gain more lives and continue with your score and phase counters intact.

When you reach 100,000 points, you get a get to enter a drawing to win Mario playing cards, and at 200,000 points, another code for a chance to win a copy of Super Mario Bros. 3.

The third mode, Name Registration, allows both players to register their name, age, and gender for use when a high score is broken and for honorifics.

The fourth mode, Notices, has a Shellcreeper explain the promotional features of Nagatanien World.

The game was a promotional release, and was only available through the Disk Writer.

Kaettekita Mario Bros. for Nintendo Entertainment System is currently worth €43.84 loose, €68.28 complete in box, and €136.60 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Kaettekita Mario Bros. has only a handful of tracked market sales, suggesting relative scarcity compared to more common Nintendo Entertainment System titles.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Kaettekita Mario Bros., loose is €43.84 and CIB is €68.28 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
