Being Political in Gaming

One problem that the video games industry has in being accepted as a mature medium for art is not one of cost, but one of avoiding controversy. Particularly in the area of politics.
The games that do get controversy, like Grand Theft Auto, tend to be focused on the violence and sexual aspects. With GTA, much of those aspects are taken from much of the cinema counterparts that the games were based on.
Unfortunately, even the industry views video games purely as an escapist medium, and not something that can tell a truly relevant experience.
Just today, as of this post, Sony decided to remove a song from its Little Big Planet soundtrack...because they thought it would have been controversial. There's very little evidence, as the link shows, to show said song would have any controversy.
The only place we get political or attemptingly relevant games are from home-brewers, single or few people that release these games. To this date, I don't think any are considered good, although some do consider them good attempts.
It's too bad that the only commercial game that does try to be relevant to current issues, well....it's basically a movie.
Hopefully gaming will shortly try, and succeed, in projecting a view or question on a current issue. Isn't that why the new Battlestar Galactica a great series?
