Nintendo in their following fiscal report :
" We'd like to announce that our subscriptions to the NSO have tripled since the last report ! It "coincidentaly" happened when we launched Tetris 99. Further more, it is clear in our minds that our studios shall now focus on developping exclusive battle royale like content on our platform. *Mario Kart Royale Course gets revealed* "
Mario Kart Battle Royale... that doesn't sound right @_@
