In one "collectible box set" (pictured) the Anthology includes the gold editions of Total Wars: * Shogun * Medieval * Medieval II * Rome * Empire (Note: this one is the Special Forces edition, not the Gold edition)
As for that bonus content for Napoleon? SEGA says it "offers exclusive Napoleon: Total War collectable artifacts including a letter from Napoleon to his generals, a map of the battle of Waterloo and six character cards." Napoleon: Total War is due out February 2010.
The best bit about all this? The price: $99.95.
The Total War Anthology goes on sale October 1, only in Australia and New Zealand.
