Update-I couldn't stand the suspense. Even though I already bought the "regular" GC2, when I saw the
COLELCTOR'S EDITION in the nice, shiny box, I had to have that too.
Both Retail off-the-shelve versions include the same sealed jewel case, and the same Game Manual.
The CE includes extra the printed Technology Tree Poster, and an additional Serial Number to d/l the CE Content.
