It's so addictive I hardly had time to write this review - I love I can come home from a long day at work and play solo!
Because I cannot count on being able to play on a regular basis, having no fees is a real plus. Also, while I really like World of Warcraft, the drain of dealing with player personalities and drama in the fantasy MMORPG world setting can be taxing after a long day at work, where I already have to deal with a lot of people/politics. In GW (both versions), I can still accomplish group-oriented missions by just "hiring" henchmen from the town and not deal with the hassle of recruiting and coordinating other players.
VERY dangerous game - I started playing on a Friday and was playing the darn game all freaken weekend!!!! Only wish: that it was easier to travel between the Tyria and Cantha continents. You really have to quest a bit before the traveling option becomes available.
