The early video game industry was marketed to kids, just look at the difference of the old nintendo powers to the new ones, this notion that video games are just a childish hobby that will be outgrown has stuck. What most people fail to realize is that video games have developed into a much more mature form of media with complex stories and themes being told and explored such as in Mass Effect, Alan's wake, Heavy Rain, or even man hunt. I think most serious video games scripts are on par or even better than some movie scripts and people have just failed to realize that it is much more mature form of media than the earlier days, i mean, sure, you have stuff like the wii which is just a fun, casual toy for the most part, but, there is other types of video games out there made for a much more mature audience than the past. This is also the reason why sex and drugs and all socially taboo things are seen as a shock in video games but not in movies or television or other forms of media, because people have not adjusted to a developing market with much more complex themes.
