Here's the Conservapedia entry on video games. As you've probably guessed, most of it's about how playing video games leads to obesity, heart attacks, dropping out of school, mass murder, and, worst of all, atheism in teenage boys and young men.
Not all is lost though, as:
"Video games have been suspected of giving otherwise liberal people some virtual conservative viewpoints. They have also been shown to help people to become more attuned to their surroundings and increase coordination, and in the future may be used to treat people with visual problems and to train soldiers."
Really? Video games make people more conservative? I mean it may happen, but the other way too, depending on the game (like every media).
