This guy is pretty cool. He takes the time to test free MMO's, so you know what's decent and what's not. He may not cover a whole lot sometimes, but it's better than a 3 minute gameplay video.

Check him out. He did a review on Dragon Oath.

Note: The Dragon Oath team themselves has added his review to their youtube account.
