I understand your perspective, but I think you are approaching it from the wrong direction.
What we need to focus on is not fewer immature power fantasies. Any individual example of the cliche are not bad when taken alone. In the world of art, most any perspective or approach is at least worth experiencing. What we need is more of what we consider (in a kneejerk way) to be artistic. We need a selection of games with strong writing, meaningful commentary, and general artistic value that is not dressed in the trappings of shallow power fantasies, however valid many games are as artistic expression through the lens of the shoot em up or beat em up. We don't really have that anywhere near the mainstream right now. But once we do, games will be accepted, no matter how many Lollipop Chainsaws we make.
Right now, movies will always be considered a valid medium, no matter how many Michael Bay movies get made, because everyone knows that movies once brought us Citizen Kane, Shindlers List, and Casablanca. Once we get a Dear Esther, The Path, Passage or Journey to propel itself into the public conscious, then even the most stogy old coot or quasi beatnik will attribute any number of 14 year old boys fantasies to Sturgeons Law.
