I can understand the (no pun intended) potential origin of the origins; many rpg players, when presented with a preset, will usually go along with that. Remember the constenation amongst 'journalists' when it was found out that something daft like 93% of Mass Effect player's went with the male shepard, with the default appearence, with the default class of Soldier? Origins is a way for players who aren't confident to get a few 'template' options for people.
