I wonder if it is really about an insurmountable scope from years of development--or is that just a red herring on the fact that a lot of developers, particularly in the AAA range, have just forgotten how to make games actually fun to play that caters to their demographics rather than casting a web to the common denominators?
What I love is that it really focuses on gameplay and player choice and options.
It's so fun to risk different rolls, etc. and different ways of doing things.
I just wish it had a day-night schedule, NPC schedules and a living world like Ultima VII / Oblivion, but it's hard to balance with the hand-crafted quests.
A lot of CRPG fans have been hoping for games that can approach the tabletop RPG experience for long time. It inevitably leads to a large scope, but I don't think that's the same as appealing to the common denominator.
