In his latest podcast, Major Nelson discussed the challenges of backwards compatibility between Xbox and Xbox 360, One that apparently has a number of difficulties of no smallaccount. Much of the work is to test the games that are transferred from the old to the new console, and each version available so that there are no problems of compatibility (GOTY and such). Another obstacle may be represented by licenses. An open world title, for example, could have a car model that is no longer valid, the license granted to the developer at the time of launch, and the same goes for music. A curious example oftechnical difficulties which may crop up: in an early version of Forza Horizon for Xbox One, the transition to the new console were entirely missing collisions between cars, and this took a huge amount of additional work for Microsoft.
