Rock, Paper, Shotgun follows up on the World of Goo sale that's currently underway allowing customers to pick their own price for 2dboy's platformer. They analyze "interesting," "significant," and even "fascinating" data on the prices gamers chose to pay (besides the over 16,000 who paid a penny), including 352 who chose the occasion of this sale to pay full price. Perhaps most striking is that 10% of the customers who gave a reason for their purchase said they were now purchasing the game after having previously pirated it. In all the game has sold about 57,000 copies during the sale for over $100,000, and 2dboy is making a note here, "huge success."
