According to Kotaku, the first episode of Penny Arcade Adventures was the highest-grossing Xbox Live Arcade debut ever, earning $330,000 in its first three days. These numbers were taken from VGChartz. The prior record-holder was Worms HD. In terms of units sold, On The Rain-Slick Precipice of Darkness was the third-highest performer of 2008 - even with its higher price point.
