The next Forza Motorsport is going to weigh in at 100GB, which makes it not only the biggest Forza title at launch, but one of the largest titles in the Xbox library. Gears of War 4 has it beat at 120GB, but I imagine that Forza will take its place once all the inevitable DLC packs are released. The massive download size is likely due to 4K assets. Barring any other games that come out between now and when Forza Motorsport 7 comes out, this is by far the biggest game on Xbox One. It might be the biggest game on any console actually. Considering that the last Forza title was around 50 GB, this is definitely a startling leap. At this point I would usually go into a diatribe about how huge games are annoying to install and I need to buy another hard drive, but Forza Motorsport 7 just looks so amazing at 4K 60 FPS that I’ll just upgrade my internet.
