I love Mario Kart, and if it was just for the racing aspect this app would be 5 stars. But it is constantly into microtransactions and grinds unnecessarily. It's basically a toddlers version of a corrupt casino. Can't support microtransactions. They are a cancer. If you have kids, don't let them play this app, and make sure you don't buy any microtransactions, it's a huge waste of money.
