The game is ok. I played it until about level 30 and it was meh.
You NEED a great computer in order to run this as it will lag you to no end. I highly suggest going on a non PVP server unless you want to be ganked 24/7. There is a lot of load times, I didn't find it immersion breaking and it gets less as you level up.
I have heard mixed reviews also, I am waiting for Warhammer Online and have already pre-ordered it.
