Turn 10 Studios have confirmed that popular racing franchise Forza has recently surpassed $1 billion in retail sales, making the game the most popular racing franchise of all time. Turn 10 Studios Head Alan Hartman broke the news today to the official Xbox One website, rounding off a incredible period for the series following the successful release of Forza Horizon 3 on both Xbox One and PC for the very first time, and the recent commitment to bring future Forza games to the Windows platform alongside it's traditional Xbox console home. "Today, we’re excited to share a major milestone – as of December 2016, the Forza franchise has exceeded $1 billion in retail sales. This news caps an amazing year. As of December, more than 14 million unique players were involved in the Forza community on Xbox One and Windows 10, the award-winning Forza Horizon 3 sold through 2.5 million units, and Forza continued its run as the best-selling racing franchise of this console generation" Said Turn 10 Studios Head Alan Hartman. Many many fans have played one Forza game or another since the title made it's Xbox debut back in 2005, created as a direct rival to the then king of racing games Sony's Gran Turismo. Over the years the franchise has steadily expanded the number of cars and tracks found in game as well as marking itself out as one of the most visually impressive racing titles on the marketplace. With 2015/16 having seen releases for Forza Motorsport 6, Forza Horizon 3 and the PC debut of Forza 6 Apex, it is little wonder that the developers are currently riding on the crest of a wave with the series. Recent years have seen a progressive decline in the quality of Gran Turismo releases, and with the Sony flagship racing game holding the position as the traditional main rival for Forza titles confidence must remain high at Turn 10. However despite the admittedly impressive sales figures achieved so for by the studio they will need to stay on top form throughout the next couple of years. With stiff competition in the shape of Project CARS 2 and the much anticipated GTR3 due to release before the end of 2018, plus the latest Gran Turismo Sport offering that should eventually break cover at some stage during the coming year, the current status quo could easily be disrupted heading into the next 24 months. Forza Motorsport 6 is available for Xbox One now. Forza Horizon 3 can be purchased for both Xbox One and Windows 10 PC. Check out the Forza Motorsport series of games forum here on RaceDepartment.
