I don't consider NWN2 even remotely a console RPG. The depth you're talking about was the product of a generation, not platform. No game since BG2 has had that depth and NWN2 is considered the deepest since that time.
Why that time is gone, I wish I knew. Is it the increasing development costs? Rise in piracy? Changes in gamer culture/opinion? Probably all of the above and then some.
In short, there's nothing to be dissapointed by.
