Forza Horizon 1 is already backwards compatible and was free on games with gold last year. You need to have a physical copy to play unless you bought it digitally before since the game and all its DLC was delisted in September of last year. I doubt either Forza 2, 3 or 4 will be added anytime soon and just like with Forza Horizon you will need to have a physical copy to play it since they never where available digitally and all their DLC's have been delisted for over a year.
