The art design:
When DA came out, people let and right were complaining about how ugly the characters and visuals were. I agreed on the characters, but playing the game on max settings for PC, I thought everything else looked stunning. There were some truly gorgeous environments in that game. In this one, they seem to have fixed the uggo syndrome, and while the first screens of the game were hideous and very unappealing, and I don't like how the Darkspawn look now, I get the feeling that with settings on max, the game will look just dandy and I'll become fond of the new style. I'm glad they overhauled the visuals, even if they took it in a different direction than I would have preferred.
UI:
I need to see more, the developer video with the first UI gameplay didn't really give me enough of a chance to decide, but I don't think I'll mind too much.
The Story:
I love the idea that it takes place over a course of ten years. The first game felt truly (and the overused word is deserved here) epic, once you reached the end of the game and saw the impact of all your decisions, it really felt like you had changed the world, moreso than any other game I can recall, and that was only over a short period of time. That feeling seems only magnified with this concept, and I think it's thrilling and brilliant.
The Characters:
I don't know enough to judge yet, but I have no doubt Bioware will craft excellent characters - they always do. Why would they stop now? Interested to see how Lilith (was that her name?) works in the story as a party member. Now, to the primary controversy - the 'Mass-Effectization' of your character. Yes, it blows that you don't have control over your character's race or origins, really making it feel like 'you.' But on the other hand, I'm open to it. I liken this to fiction: I've noticed that I don't prefer first person stories. In first person stories (this is the way I feel, not a statement), the narrator is never the true protagonist, but a lens with which to view the world in the story and the real protagonist, which the narrator is typically observing and affected by. Because of this though, I often find the first person to be a bit boring. It isn't quite you, but it isn't quite another character. Similarly, when I'm playing as 'me' in a game, there's always that disconnect - sure I'm doing these things in this world, but it's not me - I can't bridge that disconnect. I'm more interested to step into the shoes of this different character and guide their actions. It's more like a JRPG than a WRPG in this sense, this change in character perspective, and if Bioware says it's going to help them tell an involving story, I'm going to give them the benefit of the doubt. I see no reason to be wary, with their track record.
Also, I don't really mind the name Hawke.
