Play Magazine, that award goes to Richard Garriott's Tabula Rasa. An excerpt from the February 2008 issue in which the award is given, says, "... Richard Garriott's Tabula Rasa presents a compelling moral/political sci-fi yarn sprinkled with just enough clever hybrid gameplay to escape the clutches of the MMO cookie cutter. TR's instances are well written, its world designs are thoughtful, and the cloning concept provides for highly rewarding class experimentation."
I can't argue with that. I'm sure a hoary host of others will... since people love to gripe. But frankly I love the game. Then again I'm easy to please. If I don't like a game I'll stop playing it instead of ranting about how horrible it is in the general chat channel - day in and day out. Yet ironically continue to play the game. (Hmmm, can you say attention starved "griefer?") Anywho, congrats to Richard Garriott, NCsoft and Destination Games! Keep up the great work.
