WoW: WotLK - Review @ IGN

Highly regarded once again with these closing comments:

With Wrath of the Lich King, World of Warcraft's play style has been tweaked to be more accessible, addictive, and deeper. Any longtime player is sure to be pleased with what Blizzard's done here since it gives the higher level population a wealth of new content for play as well as improves the overall look of the world. And let's be honest, if you're going to spend hundreds of hours in a virtual space, it helps if it's pretty. It's an MMO system that works, as the game's success underlines, but you've got to ask yourself after four years how long this kind of momentumcan last. Perhaps within the next two years, or by the time the next World of Warcraft expansion is released, there'll be a clearer answer.

As for now, Blizzard is more than content to build on World of Warcraft's formula, improving and refining nearly every aspect of the game, delivering new quest systems, a better and more focused narrative, loads of new goals to chase by yourself or with friends, and made acclimating to its world's complexities a process generally free of the headaches of something like CCP's EVE Online. Those who've yet to jump in should absolutely do so; it's hard to imagine anyone being disappointed with such a well-run, polished product that offers so many reward strata and diverse styles of gameplay.
