This MMO is much better than WOW, and more immersive. It actually takes a great amount of skill to play the game as opposed to most other MMORPG's where hours of wasted life leveling up ridiculous amounts earn you seniority. As with most online games however, the game does require some serious grinding (playing or participating in the same way constantly).
I play it almost daily, I have slowed down however depending on my personal schedule; but I still love the game just as much as I did when I first started playing. There is tons to do, and a seemingly endless supply of expansions (over-exaggerating).

Great game if you love MMORPG's.

Side Note: WOW Sucks.
