Put me down as another person who had no idea who the heck Diana Allers' model was until they read that somewhere. TVTropes, I think. Anyway, it's painfully obvious the whole point of her character was so that the journalist could end up being in game. Never mind that Allers looked somewhere between out of place and creepy.
So, yeah. I'd like to think that the ending didn't have to be cobbled together in a rush because they wasted their time rendering IGN journalists. Most likely not, but it still doesn't make them look better.
