A couple friends bought the game a few weeks ago and when they were setting up the payment options both realized their billing periods started on May 12th for the one who bought it in december and July 16th for the one who bought it last week.
¿Do new accounts get extra-long free periods or something? If that's the case I might just buy a new copy of the game for 9€ instead of paying 48€ to play for 6 months.
