Sony says that the fastest-selling PlayStation Network game of all time is Sucker Punch's inFamous 2: Festival of Blood. It came out as the #1 game in the top 20 for the month, but it's also the all-time fastest seller on PSN. That's good to hear, because I'd like to see more of these larger offerings for download. These kinds of numbers can be encouraging to game makers, you know.
Festival of Blood even managed to beat out Saints Row 2 for the month, which is impressive when you consider that all PS3 Saints Row: The Third owners got a free copy.
Nice work, Sucker Punch.
