I think its worth it.

They added a lot since the initial start. One of the good things I am enjoing is the player housing. I have to get used to the rent type system, but other than that its interesting. I am trying to collect some cool trophies to decorate my domicile.

Another thing they have improved on is the customization of the UI. A lot more has been added to customize it. Its more/less like customizing the UI in Guild Wars. You can move and resize almost anything.

Till January 31, 2008 you can pay for 3 months (no less than 3 months when purchasing time) at $9.99 per month.
