Don't get me wrong, it's a very basic MMO.  

But it's absolutely the best game I have played on my iPad.  

The MMO is open-world. No instancing, etc.  The graphics are basic but clean.

The mechanics are pretty good.  Quests are very basic.

But the interface is fantastic considering that I am easily playing an MMO on my iPad.  Even moving while fighting works well.

I'm enjoying th eheck out of it.
