Just a couple general notes (on-topic) based on what I've seen in this thread:
-for those who played human noble females for the "happily ever after" ending, or those who suspected players did as such: You know, there IS a third option to what to do with Alistair at the Landsmeet: Not make him king, let Anora rule alone, and have Alistair continue as a Grey Warden with his love, YOUR PC Grey Warden.
(to be honest I don't ever understand how people can miss this and get so mad about having to be a human female noble or be pissed off about Alistair breaking up with you. You don't even need to harden him, either. My female Dwarf Noble rogue romanced him, did not harden him, and I successfully settled the landsmeet without Alistair having to break up with my character)
-for those who've never played/completed a dwarf playthrough or never even considered doing so: as a friendly suggestion; I recommend you give it a try at least. I'm not gonna go "master race" on you if you refuse, but all I'll say is that you may be pleasantly surprised at how much you enjoy those two origins if you try them out

.
-for Gaider (since he's been on here the most out of all the devs): is it incorrect to assume that telemetry data is continually building even as DA2 is released and that future DAO playthroughs, combined with DA2 playthroughs, will give additional insight into what people may want for the future of the Dragon Age franchise?
Those out of the way, personally I have done at least one playthrough per origin, and found it easy to do so since for every type of character one could do, I am able (with my active imagination) to easily create a character personality concept in my mind and find ways to roleplay that type of character. The only origin I have played twice (to my deepest regrets) that are still logged in is the Human Noble origin. I deleted one of my characters, though, so now its just down to one human noble.
out of all the origins, my favorites were the City Elf, Dwarf Noble, and Dwarf Commoner, and Dwarf Orlesian Warden (because I like how the "anti-Orlais" sentiment was implemented in Awakening). I started with the City Elf, and I may play that origin again due to the awesome story, but from here on out my future playthroughs will be all dwarves.
My least-favorite Origins have to be the Dalish Elf origin (hated that I wanted to roleplay a badass and ended up only able to roleplay a wuss. I also hated Tamlen with a passion), and the Human Noble origin (used to not be so bad, but a major glitch in Origins and Awakening has turned me off permanently to the origin)
