it's completely free, you will get a "gold member account" which means nothing because thats what everybody gets. it takes a long time to download client and maybe when u install and try start playing u will have problems either starting or entering the servers. check your antivirus program and firewall if u try and it doesnt work. for the best server to enter, i would say go to the newest, Bango, because Hanin is dead and Naraeha was born a year ago so its already to old for new players.

hope it helps

its not free if you want to lvl up fast. the lvl system sucks and you need exp stones just to get to the lvl you want
