Urm. I'm not really sure what you are asking.
There is Flight Simulator X and Flight Simulator X: Deluxe Edition
Both are on DVDs... CDs are incapable of holding this much data without you buying (guesstimate) 50 of them in the pack.
The difference is that the Deluxe edition contains 6 more aircraft by default (24 as apose to 18 in regular) 5 more high detailed airports and 10 more high detailed cities than in the regular.
Wikipedia comparisonHope this is what you meant.
