Turn 10 Studios announced today that prize crates—Forza's take on loot boxes that deliver a randomized selection of cars, mods, gear, and badges—will be removed from Forza Motorsport 7. The studio also said that tokens, an in-game currency from previous games that must be purchased with real money, won't be added to the game, or to the upcoming Forza Horizon 4. 

"While we’ve never charged money for prize crates in Forza Motorsport 7, their presence in the game has continued to be a source of controversy. The overwhelming feedback has been that this system feels out of place in the game. After careful consideration, we have decided to completely remove prize crates from Forza Motorsport 7," Turn 10 studio head Alan Hartman wrote.
