It is perfectly conceivable that, in the future, a true once-in-a-generation creative mind ends up at a video game studio and creates a game that changes the way people think. Games like Black and White arguably have done it to some extent in a small percentage of people.
Video games are a unique medium in that the player shapes his or her own experience; this may make video games ultimately more influential on people's lives than any other form of art. And while we're talking about other forms of art, let's not forget that a lot of video games have original scores. Most of them are not that great yet, but as less and less people care about the Opera, the new composers will have to go somewhere else, and why not Relic?
The notion that one form of art is superior to another is elitist nonsense.
Let's not forget that the contribution of video games on the "collective of people's lives" is mainly negative. In this particular example, these politicians link themselves to Starcraft, which might be a good tool to increase their share of potential voters amongst young people that are allowed to vote, but does not go well with solving the various issues surrounding video games.
However, imagine these politicians would link themselves to the most popular game in Sweden: CS:GO. A politician cannot uphold his/hers integrity while promoting a violent video game and take a strong stand on the current situation in the Middle-East.
There are political parties (Piratpartiet in Sweden, Piratenpartij in The Netherlands) where one of the main political goals is to increase the rights of the average internet user. This is a much better way to combine video games and politics.
