Well i think they should have just made the competetion all halo maps except, Sanctuary Ivory Tower and BloodGultch/Coagulation. I mean all the PC exclusive H2 Vista exclusive and DLC are still in halo. Tombstone wouldn't really matter its just Hang Em High with a few things added, Desolation however is very different from Derelict.
