The CE comes with a bunch of things.

Really nice!

BTW, this is a MMO game.

From Amazon:

Players who purchase the Limited Collector's Edition box also receive a briefing from Richard Garriott's alter-ego in the game, General British, classified maps, an Allied Free Sentients (AFS) field guide, Tabula Rasa dog tags, an AFS challenge coin and a special edition poster. The Limited Collector’s Edition also includes one month of
free game play and a "Making of Tabula Rasa" DVD.

I heard the game was awful.

Garriot has done nothing but stumble all over himself ever since he left the Ultima series.

yes 1 free month included!
