I played it back in last stages of beta and for very short time after it went live, maybe two months.
It was a really good looking game at the time, the only issue I had with it was that there idea of pvp was not very good. you had to be a certain level to unlock the ability to create a "monster" char to be able to fight against other players chars using their main chars. So it was always one sided. You create a worg for example and it has nothing but basic attack moves, while trying to play against players that have magic armor and weapons. It only worked in one zone which any player char that traveled there was already equip and ready to fight the "monsters".
As far as pve goes, it was pretty good back then. It had one of the first real use of phasing in a mmo, where quest or some other type of trigger would phase into a story scene without affecting other players around you.
Been meaning to go and check it out since it has went play for free. Game should be hugely different now, after so many updates and 2 xpacs. Let me know what ya think of it if you are playing or will be playing it soon.
