If you're grabbing Super Mario 3D All-Stars as soon as it launches, get ready for a day-one update to be available as well. We're not quite sure what the update does, as patch notes are yet to be shared. We do know that it bumps the game up to Version 1.0.1.
UPDATE - While official notes still haven't been shared, we're hearing this update tweaks Super Mario Galaxy's textures to include more button prompt texture overrides, and all fonts have been updated.
