Not trying to call you out bro but are you reading what your writing? A game is meant for entertainment: fun = them doing their jobs. If I want something intelligent I'll read a quantum physics textbook. And honestly, I don't mind, in fact I rather like the story to be simple in video games. Simple doesn't have to mean childish or cliche. I don't particularly enjoy the way bioware (and other developers?) is moving, where they try and create these tough/morally ambigious choices for the player to make. That kind of crap stresses me out. Sure I guess in some sense it creates a more personal and engaging story but really in my mind it creates doubt, confusion, and ultimately the choice has no real consequence in many cases.
That's a pretty narrow view of entertainment you got there. I certainly have more fun with a piece of entertainment which challenges me emotionally, then one that doesn't.
