"Mario Kart" has always been exclusive to Nintendo's gaming platforms over the years, with emulators also getting access to older game versions. The good news is YouTube now has a version of the game.
The game went live on YouTube last June and is accessible through any web browser on desktop. It is a browser-based racing experience built natively into the platform, and it appears to be a promotional tie-in for "Mario Kart World" on the Nintendo Switch 2.
