Christian, do you feel it's more mature when comics are called "graphic novels"? I hear that and think "Nice try, comic book kids." In my opinion, if you try to call video games something different to make it appear more mature it'll only call attention to the fact that you're forcing it. This is why you don't wear a tie to your first day of high school, everyone who knew you in middle school will see it for what it is. Rather than gussy it up, let the content speak for itself.
