I used to play this MMORPG everyday. It was so much addictive. However, in my point of view, the community of nowadays is kind of dead, it isn't what it used to be before 2007, for example.
In my opinion, the strongest point of this game is the PVP, also known as PKing. You can have lots of fun playing with a clan, go on trips and talk with them on the forums. There are some good clans out there with friendly people that makes this game enjoyable. Although, as I said before, it was better a few years ago.
