I very much agree to the first statement, and, at least partly disagree to your second statement. There are very few pieces of fiction that achieve to present "both sides of a story" without emphazising either the one or the other. I'm not saying it's not possible, but I'm saying it's difficult. In the case of games it seems to be even more difficult, because of their interactive nature. I can read a book or watch a movie without really getting involved. I do not have to like the main characters or their actions. I do not have to act, but can be just a mere observer. In a video game however, I have to act, and therefore will usually be forced to take sides.
