I played since head start, it had a lot of the same feel as wow on some things but other things were just leaps and bounds above wow, i.e. the class system. The game was very polished at launch, I played for a good 6 months till I got married but I have friends that still play and the7 love it. The end game was great, they released new content at least every 1-2 months, and pvp while like all mmo's was sometimes unblalanced it was still very fun.
I think its selling for only $19.99 which includes of course the first month free. Your probably paying $15 a month for wow anyways so for $5 you can try a new game.
Some of the landscapes are just sunningly beautiful, though I have a good video card. I say go for it, you will enjoy it.
