Found this on Gamespy. It's a review by some guy calling himself "the Resident Cynic". I dont' spent much time at Gamespy, so don't know if this guy knows what he's talking about or not, but he wrote an interesting review on WoW.
The review can be found here.
What I liked about the review, admits that WoW doesn't push the boundries of the genre, doesn't push the boundries of the computer, but it's just a fun game.
In the end, isn't that all we really care about..
that it's a fun game.
