Will players have to pay now to play or not?

I have been playing ff 14 for about a week and have not been asked to sign up for a monthly subscription? If I can play for free, I won't complain, but when will I be required to pay to play? That is my question. I have the downloaded PC version from Amazon.com and I have registered with square nix.

If you just bought it a week ago then you still have 2 more weeks of free play

Yea just like every other P2P MMO that has a sub fee, when you purchase the game ur first month is already included.
