Nintendo recently officially launched the Version 1.4.0 update for the Switch’s “Super Mario Galaxy 2”. The biggest focus is not on fixing bugs or improving the graphics, but on directly adding a new storybook chapter as the final ending of the original story (thunder).
Nintendo suddenly completed the ending, old players were shocked and then moved
The “Super Mario Galaxy” series has always been regarded as one of the golden masterpieces of 3D Mario. Since its debut in the Wii era, the two generations of works have been listed on the top list of the series by many players for many years due to their creative level design, planet gravity gameplay and musical atmosphere. Especially the storybook plot of the first generation made Rosalina one of the most popular characters in the series.
How to unlock? Official conditions made public
According to the official description, if players want to see this new content, they need to complete the end of the original storybook first, and then clear any planet and obtain a star to unlock the new chapter.

The update is not only about the content, but also the official optimization.
In addition to the new final ending, this 1.4.0 update also includes some minor adjustments, which are officially described as providing a “smoother gaming experience” on the Switch console. Although no specific correction projects have been disclosed, such descriptions usually represent further fine-tuning in loading, stability, detailed performance, etc.
Why update now? The answer is actually the 40th anniversary plan
The timing of this update is not random. 2026 marks the 40th anniversary of the Mario series. Nintendo has recently launched a number of related projects, including released movie versions, re-releases of old games, new releases and additional NSO classics.

Rosalina’s popularity is high, and the Galaxy series is once again on the table
The “Super Mario Galaxy” movie version has recently made Rosalina once again the focus of the game, and after the two games in the “Galaxy” series have returned to the market, Nintendo naturally knows that players are still thinking about this branch universe.

Therefore, the addition of the final ending to “Super Mario Galaxy 2” this time is likely not just an Easter egg, but a test to see whether the market is still enthusiastic about the Galaxy series. If players react enthusiastically enough, who’s to say there won’t be a Super Mario Galaxy 3 in the future?
