Forza games have a four year live cycle due to some of the DLC cars licenses expiring after four years that is why Forza Horizon got delisted last year and Forza Motorsports 5 got delisted last month.   But the online suport last a lot longer then that since I'm pretty sure you still can play Forza Motorsports 3 online and all newer games in the series.   

You sure about that? You know the Xbox One and OG XBox are nothing more than PC hardware, if MS really wanted they could allow you to play every game.

Difference is you dont have pay for them

I would play Ninja Gaidern Black if it showed up on Games with Gold even though it doesn't have achievements. Also would be nice if the could add the first Forza Motorsports in the second update but I doubt that would happen since that game probably has over a dozen cars with expired licenses. Red Dead Revolver would also be a good option for the second batch of titles.

That is if you still have the disc.

What else have excepted from Backwards compatibility? 

I beat it and got most of the achievements for it.  It only a slight improvement over the original version.  I think they could have done a much better job with it if they really wanted to.  The major flaw is that it still has tons of long loading times.  Plus the game is proned to crash once in a while. 

The X1 doesn't play games off the disc once you pop in the disc you download the game digitally on you HDD. 

Totally agree the firs one is still the best the second one is still pretty good I liked the additon of the dog.  The third one is way to easy although I still kinda liked it so I don't hate it as much as most people.   

Is that game BC on xb1?
