Setting the bar to 17+ for the age requirement means we don't really have to worry about any legal issues to giving games away rated anywhere from E to M. While I know this isn't something a lot would like to see, please try to understand our perspective on the matter.
When you enter our competition you are agreeing that you are of age 17 or older. If you are not and any legal issues result from said entry then we are covered since it was the requirement for our competition.
We add the ability for permission from a parent/guardian to allow those that want to enter the ability to enter. Your parent/guardian giving us permission is the same as saying "We're fine with this person potentially getting a M-rated game".
We will take any feedback given in to consideration for future competitions. However, for now the age requirement will not be changing.
