I never saw Darkfall. This game looks great but looks very Beta at the moment. It is still in Beta but I thought it would be further along. There were only people, deer, and a weasel in the vicinity when I saw him play, but he didn't venture too far I guess. There was player housing though. It used the red-blue-grey and ghosts/healers like UO and I saw two reds kerpwn him but not much else.
It looks worth checking out but I don't want to pay for it until the super dedicated debug it for me.
