Obsidian has some skill with RPGs no doubt about it but they NEVER lived up to the greatness of the previous games. They did KoTOR II and Neverwinter Nights 2 and I have to say that the fans really felt short changed. Fallout 3 at the moment is the shining pride of Bethesda while TES: Oblivion has already ruined the TES series so why not give them something else, something less important and already ruined.....like.....oh I don't know......TES V for example?
At this point I feel very strongly that Bethesda should be making this game so that the fans can continue to enjoy this great series rather that prepare for a huge dissapointment.
I don't know what you're talking about, KotOR II was great, as was Mask of the Betrayer. They both at least lived up to their predecessors, if failing to better them (the KotOR II "ending" notwithstanding").
Actually NWN2 is really an aberration. I honestly don't know how the same guys that, once upon a time, had a hand in Plancescape: Torment, Icewind Dale, and Fallout managed to make that.
Incidentally, are you the same Darth Trethon on the Mass Effect forums?
