I have no idea why of the many promotions that are ran to get players to buy a month, six months, or a years membership, there isn't a promotion that allows a one month, six month, or a years membership to both games at the regular price of one game, or at a nice discount.

This option alone would surely pack players into Pirate101 who otherwise do not play it, have played it but gave up on it long ago, or simply have not ever tried it.
