Right. I just wanted to make sure I wouldn't be violating any rules/policies having the mmo server verifying game purchase/profile info using the player's api key.
Thank you! It turns out, after going through the API some more. Since its a free game, it will never show up as owned/purchased via API, so there is no way to determine if a person owns a copy of the game via API. So that part is worthless in my case. However, the user_id is as different story, so I can at least check that.
Thank you for your replies.
