The Playground Games team announced earlier today on Twitter and the Forza forums that 2016’s Forza Horizon 3 will be racing off into the sunset on September 27th, 2020. As they’ve done with previous installments in the series, Forza Horizon 3 will be on sale until it reaches “end of life” status on the 27th at which time the game and all of its DLC will be removed from digital stores.
Online features and multiplayer will continue to work after the deadline and anyone who previously purchased it will still be able to re-download the game. Of course, Forza Horizon 3 was released physically so copies for Xbox One are still available out there.
I’ve added the date to the Watch List calendar and will have a page up on the site soon. Thanks to @pasta_wheat for pointing out the news!
