Xbox One owners who enjoy a nice discount should check out this deal. Between now and September 30, you can get a year's subscription to Xbox Game Pass, plus copies of Forza Horizon 3 and Forza Motorsport 7 to keep, for $99. Considering a 12-month Game Pass subscription alone normally costs $120, that's a seriously great deal even if you're not into racing games. You can get the deal here.

But for those who are into racing games, you'll also be able to play Forza Horizon 4 for free when it launches on October 2. That's because it's a Microsoft-published game, and all first-party games are included in Xbox Game Pass at launch.
