While Forge is not available for the PC, the team plans to "transfer" one-off Forge cards and game types "once" from players' file shares to incorporate them into MCC . If you had a preferred Halo 3 Halo 4 or Halo: Reach custom map, you may be able to play this in a revised form.

Although there is no guarantee that you will see everything you ever had, you probably will not be limited to the basic version of each game.
