i played it for 3 years until i got bored of it. the Story is amazing... a lot better than WoWs, and the PvP is extremely fun. The only problem, is there is very limited content, and thats y i play WoW now. the no story part (by no story i mean not much, definantly not as much as is involved with GW), but there is a lot to do.
I recomend getting GW, if you play it for a few months its worth it. 20$ for a life time to play, with no subscription..
