I have all the additions to Forza for free in the cloud game.

Also purchased Forza Horizon 2 Fast & Furious Car Pack which stated "Once the pack is purchased, you are granted a one-time only, free addition of each car to your Forza Horizon 2 garage, with no additional in-game credit cost." However, when checking the
garage in the game, the cars are not present. But, I can access the cars and "purchase" the cars still with enough in game credits. They were supposed to be a free in game addition.

Did anyone answer this issue?

I would not use the cloud at all for any Forza game. Ever.

As others have said , basically all day one editions were upgraded to include a game. The fifa addition is a digital download and the forza version will be a physical disk version.

I did ask if I would be able to swap from fifa to forza and was told in store no ... and you basically got a bundle assigned to you depending on when you ordered. At least thats what they told me. I added Forza though to my epic pack as my additional free
game.

I was hoping perhaps when I went in to pay today that they would at least give me the extra bits to take home with me like forza , blu rays and play n charge pack but nooooo the bums would not let me lol.

Teased me with putting all the stuff in a bag next to the console too

For now, the cloud is mostly free dedicated servers for developers to use and, in Forza 5, the cloud takes everyone's driving behavior and uses it to create more realistic AI than you'd normally have.

All add me as well. Ive sent request to all in this thread. Im loving the "Rivals" additions in Golf and Forza, but I also have several other games.
