Age Requirement for M games online?:

It wasn't illegal for you to buy games under rated M. It's just a choice by the retailers to not sell to people under the age of 17. A lot of smaller chains wouldn't care. 

Also you can register an Origin and Steam account no problem. I think their minimum is like 13 years old.

So? Change the email on that one to something else and make a new one.

(that's of couse if you dont have anything worthwhile on that account)

you can easily find that information on your own.

Isn't mature 17+ anyways.  Also where did you buy it? I didn't think DAO required a origin account.  I mean if you're super worried go on EA customer support

You should be fine.  You are 17 years old so you should have no problem registering an M rated game because your birthdate on your origin account should say you are 17 too.
