Nintendo recently sent Japanese gamers a marketing email for Mario Strikers: Battle League but there was a major typo in the subject line where the game was referred to as Mario Kart Strikers. Users flocked to social media to share amusing comments and the possibility of what the a Mario Kart Strikers would be like, some even thought that there was a new Mario Kart game coming to Nintendo Switch. Interestingly, the company sent out an apology email for their mistake, which is a real rarity.

Wouldn’t surprise me if someone in Nintendo is trying to ask the dev teams if “Mario Kart Strikers” can be a real thing (that or someone is considering a proof of concept).๐
