It's worth it if you don't have any new rpg to play. Be warned though this game is really huge. As huge as world of warcraft. In fact, this game reminds me of world of warcraft. So you will take quite a long time to finish this game.
However, the developer of this game has gone bankrupt. So I'm not sure where your money will go.
