Alright, I know the age rules, but I have a question: Would a MATURE 14-year old with his father playing meet a lot of criticism?
Just so you know, the 18+ and associated rules has nothing to do with criticism of age. It has everything to do with liability, legality, and responsibility.
That said I believe the set in stone rule is 18+, with 16+ being allowed if vouched for by a reliable source. Correct me if I am wrong.
Sorry to be the spoiler of hope, but I am quite sure if these OPs are successful (and they certainly have been from my perspective), then you should expect to see them continue until you are 16 with a potential vouch.
