The Behemoth has announced that the special Live Arcade Castle Crashers released about three years ago has reached a staggering 2 million copies, in this case digital sales at all: in fact the statistic is accurate and is based on unique gamertags who have made the acquisition and the leaderboard of players, unlike other publishers who announce the total copies distributed in chains and stores. The result is even more amazing because it concerns an arcade title available in digital delivery and even the creators did not expect such a result, demonstrating the continued expansion of this market.
