Not if the player doesn't want them to be. My character isn't going to be dragonborn. I don't care if I have to ignore the main questline and kill any NPC that calls me 'Dovahkiin'... it's my character - I decide who they are.
Seems a waste of a good RPG IMO ~to just treat it as a digital larp, and ignore the intended experience, and careful work by the developers. :shrug: ~However... they do make the game still work (on some level), should the player choose to forgo the main story element of the game.
Yeah, I hate that. Bethesda should distance themselves from the Mass Effect style of RPG. Skyrim doesn't need an equivalent of Commander Shepard.
I have never played Mass Effect (1 or 2), but I generally find that an assigned character allows for a richer, more involved (and believable) story in RPGs.
Most of my favorite RPGs are this way; Planescape, Witcher, Arx (somewhat),
even Blood (though its not really intended as an RPG).
