It appears that Mario Kart World and Nintendo Switch 2 Welcome Tour have seen a reduction in their final file size.

According to My Nintendo Store, Mario Kart World requires 21.9GB of space. This is a 1.5GB drop from the 23.4GB file size that was originally listed in April 2025.

Another title, Nintendo Switch 2 Welcome Tour, has received a hefty file size reduction as well, from 2GB to 1.5GB.

These file size reductions should come as a good news as Nintendo Switch 2 games take up a lot of space.
