Not every game in the series is included in the collection, as the four The Elder Scrolls Travels cell phone games and An Elder Scrolls Legend: Battlespire are missing from the package. Bethesda says this is the first time it's put together a PC collection of The Elder Scrolls games, which began with Arena's launch in 1994.
The Elder Scrolls Anthology will also feature five physical maps depicting the lands of Tamriel, Iliac Bay, Morrowind, Cyrodiil and Skyrim.

I think this is a really cool release of Elder Scrolls, I am always a sucker for map posters, as the walls around my computer are covered with them...sooo I think that is the reason why this is so insanely awesome!
