As I was reminiscing with my girl friend and on the subject of video games, we came to the realization that there's really only one video game out there. That game simply has a variety of titles, graphics and subtle game play variations. I'm not going to get into detail about what that game is, but I think I have an idea where it came from...
For most people in the 'western world' all of a game's creators receive basically the same education. They might go to college for that education, they might learn on the job from those that got this education, but ultimately the exact same information regarding game creation is passed down, and if you variate from that, even a little bit, you're either fired or given an F for fail. Because people are punished for being different we end up playing the exact same game over and over again.
