If you look at the picture of the box real carefully Unknown, it says "20 Additional Missions included!." Now some of these could be Templar, or those expansion missions from a patch a long time ago, or they could be 20 new missions designed for the 20th aniversary of Interplay. Im starting to think its the former though.
Regardless if there is new content or not, I still want the CDs, the mve Cutscenes... ALL of them, and an item that will gain lots of value over the next few years. If you buy 2 copies, in a year you could sell the second copy brandnew on ebay for 3-4 times as much.
