"GRID offers a number of events with various races within them to attempt, eventually leading up to Showdowns. These events include Touring, Stock, Tuner, and GT races as well as a Fernando Alonso career line of races where you challenge his esports team. Once you complete four showdowns you can enter the GRID World Series and truly prove your skills. Of course, there are means to tweak the difficulty to make it easier or harder, depending on your skills and tastes."
