Voodoo Extreme has a review of Warhammer Online through the first twenty levels of gameplay.  They get into the meat and potatoes of what RvR, Publics Quests, and other great WAR features are all about:

I'm a big fan of Mythic. I literally have over two years of /played time in its other MMORPG - Dark Age of Camelot. Sadly, I can't get that time back, but on the bright side - I probably saved a ton of money by not doing crazy stuff like going out and having a life for so long (that's what I tell myself at least). I have sampled other massively multi-player games like World of WarCraft and Age of Conan, but never really got hooked on them for more than a month or two. Will Warhammer Online put me back in the gaming rehab clinic? Time will tell; here's my review of the first 20 levels.

They also were kind enough to pay heed to the fact that WoW looks a lot like WAR, not the other way around :).  Share with us your thoughts on the review and your experiences for the first 20 levels.
