It will probably offer only a small percentage of the playability of a full mario kart game but work as advertising for the Switch console where you can play the full game. They ought to offer a free android spectator box in the app where people can just virtually watch mario kart players on Switches play the full game online. When friends are playing online they get a message so they can watch, or if they are in the lead etc. The app should just be a training course in driving in mario kart, a sort of beginners course plus spectating of switch online games. That way it motivates people to buy a Switch console. Something like that anyway where it makes a connection with a wider audience which will lead many to buy Switch consoles and mario kart.
