But where's the npc interaction? The only thing we've heard about this is how conversations are handled is improved. I'd be the first to point out every open world game in the last 3 years has improved upon what Oblivion did in this regard. Even GTA4 had better npc interaction and more interesting morale choices to make. I'm not saying any one way to do this is the correct way, I'm just saying that even non roleplaying games have advanced to the point of having good npc interaction and I've yet to see Skyrim present much of any improvement.
The last thing I can think of is other ways of evolving your character besides stats. The character creator sounds better, but it doesn't sound as good as Eve's "Incarna" or the now defunct APB's character creator, or Fable's awesome way of letting you modify your character continuously over the course of the game.
Prototype, Red Faction, and Borderlands had virtually no NPC interaction, other than people to either kill, not kill, or give quests. GTA4 only went one or two steps further by giving you the choice of actually talking to SOME NPCs. You can't talk to every NPC, like in TES games, but you can talk to SOME. Fable is a terrible example, because if you shake hands with someone long enough, then go dig up some obscure item in the wilderness for them, they will become your friend and love you forever? How is this a good example of interaction? Dragon Age 2 didn't have any NPC interaction other than quest givers/shop owners/team mates. Most NPCs would say a little snippet, but that was about it. Conversations with your team mates were decent, but ten people in the whole game world? Come on. Even other RPG giants grant very little NPC interaction. I played FFXIII for over twelve hours, and I didn't interact with any NPCs that I wasn't supposed to kill.
TES has never supported itself as being a "moral choice" game type. The original Fable picked that as it's handle in the hopes that it would make it a "Morrowind killer," and it failed miserably by being short an unsatisfying. To me, moral choices shouldn't be limited to, "do I fart at this person, or do I do a little stupid dance for them?" GTA is a great game series for moral choices. "Do I pay the hoker for six, and leave, or pay the hoker for six, then run her over and get my money back?"
How can you modify your character besides stats? You can chose different types of armor, clothing, weapons, magic, etc. You can chose to go around slaughtering every Orc you find, while giving gold to Dunmer just for the hell of it. You could sleep every day for eight hours, or go the ENTIRE GAME without sleeping. For your examples, Incarna just seems to be a glorified dress up game. APB seems to be based on what Oblivion did. Fable has continued to dumb down the "modification" of your character through each incarnation, forcing you to become taller if you become more skilled. How does shooting a gun more make me taller? What if I want to be short, but be a crack sniper? Fable says no way.
Heck, if that isn't enough customization for you, get the PC version and download the construction set. What other developer GIVES AWAY it's source code FOR FREE? Bethesda knows they can't please all the people all the time, so they give people the opportunity to please themselves. What more could you ask for?
Comparing TES to other RPGs is akin to comparing some woodshop [censored]/bong made by a high school burnout to the work of Michelangelo. Bethesda puts so much work into producing a quality product that is steeped in lore, and opportunity. I can't think of any other company that goes to such lengths to please their consumers, who turn around and challenge their products MONTHS before it comes out.
