If I buy a used physical copy of the FM3 Ultimate Collection, will I be able to install the extra content or were they single-use DLC codes?
Should be single-use. Bigger problem is with Rewards because you won’t get many points.
Yes, Forza 3 DLC is on an extra disc.
That’s true! I have it but I am not sure if anything else was there. Forza 4 was with codes for sure.
