I have been sucked into reading the forums for hours on this game....
The things the beta testers are saying have me giddy. The skill system (gems) looks amazing and I hear that there is a very big passive skill tree that you will invest into also. It sounds like there will be tons of different ways to play your character.
I couldn't be more excited for a game like this, thanks Leevers for posting about it, I had no idea!! This game is custom made for me.
