You know why games like Skyrim, Batman: Arkham City and Xenoblade are so damn near perfect? It's because there are two kinds of players. There are those that say, "Fuck your linear plot. I'm going to see what's over here," and there are those that say, "Fuck that shit over here, I just want to get on with the plot." Those games can appeal to both, and it makes everyone happy. They're very liberal about the game/gamer relationship.
But some games want you to do as you're told, and have no problem letting you know when you're venturing outside of the realm of their intended manner of play. It's their way of saying, "Quit being an asshole and rescue the princess like we said to." And then of course, there are the best kinds of reprimands, those that deal with piracy the only way that frustrated game designers with demented minds can, by screwing with you. Both magnificent bastards will be featured here.
