I was surprised to learn that I couldn’t change my companions’ armor in Dragon Age II. I shouldn’t have been: when I spoke to Matt Goldman for a series of previews I published on Destructoid, he let it slip.
“And, basically, to confer the advantages of having that one really good design on all of our characters, we made certain decisions: to limit the amount of changes you could do on them. They evolve as the story evolves, rather than when you decided to give them different gloves, for instance. Which, I think is a stronger motivation for changing their appearance.”
