They finally are offering a 10 day trial, I installed it yesterday and played for a few hours.
So far it's very cool, still a little buggy but minor stuff, nothing that is a deal breaker to me. I especially like the combat system, basically you switch to an aiming mode which makes it very fps like though you can fight from 3rd person, it seems a great way to balance rpg and shooter game play. The environments are well done though not as debris filled as Fallout.
I've only spent a few minutes with the crafting system but it's a very different take on it.
All in all I would say it's a very good choice for while we all wait for a fallout mmo to be made.
