Yeah, well, I like Biowares stories, characters, and world. I'm not interested in blank state protagonists, and my play style is just as valid as anyone-else's. I want the choice to be able to play as a protagonist like Hawke. A lot of blank-state fans need to realise: that they are not, the only type of people, who play this game.
I'm torn. On the one hand I feel just like you and would be glad to see it reflected in the games. On the other hand I also understand (in theory) those people who want a blank character to fill with their own ideas. I do understand how a character with a personality can break immersion for others. And while I want the devs to regard my wishes, I also know that there's other gamers who also want that too; only they want the opposite.
If they could do what you suggest -- allow the player to choose what character s/he wants to be -- that would be perfect. But I bet it would be damn expensive for them. So the realist in me does not see that happen.
I don't think DAO was blank slate. There was a lot to work with in the origin stories. <snip>
That is true, they gave you plenty of backstory to work with. I did notice how they defined your character there. The Dalish (first origin story I played) had Tamlen and at least for a female it was implied he was rather a boyfriend than a friend. The circle mage got Cullen's infatuation and the imprisonment, the city elf had the arranged marriage. I did not play other origins, so I don't know about the rest.
I couldn't pick a favorite. But I assume the mage background impressed me most, because this concept of spending your whole life in a tower, behind walls, locked away from the rest of the world, constantly watched and without the right to self-determination... that really got me bad and I remember thinking about it a lot. I assume that's why my mage ended up my canon Warden, though I don't usually enjoy mage gameplay (for DAO it made no difference though, because it was so close to turn based RPG combat anyway).
But that's background, that's not so much character. Hawke had a stronger personality. And I think the conversation wheel itself is a factor. The protagonist will never say exactly what you pick as an option, so at least I was sometimes in for a surprise about what really came out in the end. I personally enjoyed that and I have absolutely no problem with identifying with a character I like. I can play GTA4 and basically become Nico for the time being. So self-insertion for me does not at all require a blank character. But I do see how other people can have a real problem with handling a fleshed out character.
