Unlike most of the people here,I played it for quite a while. I quit at 103 in December.

Pvp is awesome. Def. worth trying. Downside; GM's are effing up badly.
RvR is about at 60vs60 instead of 100+ vs 100+
The RvR is sorta like FEZ but different.

Give it a shot. I'd say It gets boring around level 50 to be honest but It picks up It's pace again around 70.

As people said,Point click game but optional WASD. Kinda crappy but manageable.
I played with both at the same time.
