NASCAR '15 is now available on Steam, offering the latest installment in the official game of the auto racing series. Word is: "Featuring the 2015 NASCAR Sprint Cup Series season, NASCAR '15 is the officially licensed racing simulation game. Includes Quick Race, Career and Multiplayer modes." There's also a playable demo on Steam (thanks Frans) offering a test drive. There's no description of the demo, but the top current review helps understand what it includes: "Gives you Charlotte (both day and night). Drives the same as last year's game in terms of car handling. The true test is how the multiplayer lobbies work this year and unfortunately, you cannot know that by playing the demo."
