That makes the tag system seem pretty broken in its current form. In Dragon Age: Origins, they gave you a custom character, and gave you the opportunity to add flavour to the custom character by having an origin.

Ideally, the tag system in D:OS2 would provide the opportunity to play a custom character like in Dragon Age, [I]plus[I] provide the choice of playing as an NPC like Morrigan or Alistair. That would be pretty cool, assuming Larian can do a good job of making compelling characters.

It really seems D:OS2 is built primarily for the predefined characters, and custom characters are just tacked on as an afterthought. I don't know if I should be excited about a tacked-on feature.
