After downloading it for free to try out, I decided it was definitely worth paying money for because this is a delightful concept and me and my long distance gaming buddies have been having a great time with it. It's a nice low pressure way to introduce epistolary RPGs, since it doesn't require your recipient to mail anything back (it's so hard to get other people to mail you back T_T), and it's delightful that the process of putting the card through the mail is actually an integral game mechanic, and it's just a fantastic excuse to draw SO MANY MONSTERS.
