According to the Federal Lottery Law, it is illegal to operate a lottery through the mail or over the telephone. A lottery exists when you must pay for a chance to win a prize. The prize could range from money to jewelry or a new car. The chance means an opportunity to win, such as a drawing or a matching lucky number. Consideration means some sort of payment by you. If all three elements of payment, chance, and prize are present, it's a lottery.
drmike: First of all; LOTTERY OF SORTS,
second, as far as I've seen they get their money's worth, they haven't paid for a chance.. If the outcome doesn't please them, how is it GOG's fault?
