Online age restriction per country - Ukrainian PSN account, reside in Slovakia.
As per this article I understand, that kids can't play online, due to EA policy:

Here is the question - this restriction works based on PSN account information, or based on my physical location?
So, for example, I'm from Ukraine, I have Ukrainian PSN account, but now I live in Slovakia. So will my son not be able to play till he is 16, according to Slovakia age restriction, or is it 13, as Ukraine is not listed, so it match with "Other than above: 13" statement?
Thanks.
Ok, I will answer to my own question - 16+ age is required, event if it's Ukrainian account.
It's logically, I'm agree.
