I'm honestly looking forward to this. The first Two Worlds, while unpolished and somewhat lacking, was exactly what I'd been looking for for some time: A third person action RPG in the style of Diablo 2. Obviously it had it's flaws--bugs, imbalances, and poor graphics--but I really liked what the ideas behind it.
If they really fleshed the idea of the first game out, I think they could come up with something completely revolutionary.
Granted, I still play a lot of D2 Eastern Sun, so I might be somewhat biased towards ARPGs.
