Cataclysm has put a fresh face on World of Warcraft, bringing not only new content and storylines, but a more refined sense of humor, new races, and changes that make the game simply more fun to play. The added high-level content is challenging, and is likely to add more hours of gameplay, especially after reaching the level cap, than either of the two expansions that came before. While long-distance travel has become a nuisance, and questing can still drag you into a grind, Blizzard has really outdone itself with the quality and quantity of this upgrade.
