So how does the US deal with age restricted games? I find this much more related to actually willing to implement a rule, rather than having rules for the sake of it (like the US buying alcohol rule - it is forbidden for people under 21 to drink but 40% of the people between 18 and 21 drink ?! source: https://en.wikipedia.org/wiki/Alcohol_consumption_by_youth_i...).
Not sure I get it. And it's different in Europe?
e.g. 20% of all 15 year old in the UK have at least one drink each week:

Despite the legal age being 18.
Also what does this have to do with anything? e.g. adult-only games are simply unavailable on Steam in Germany. It doesn't matter at all how old you are.
