The Behemoth took the time out of its busy Crying Sugar Cube Leprechaun (not real title) development to reveal that the Castle Crashers leaderboards have passed 900,000 users. That does not mean there have been nearly a million sales of the game, but it does mean that Castle Crashers has been doing well on XBLA, a mere 8 months after launch.
The company's site is now challenging users to guess the exact date and time that the main Castle Crashers leaderboard will hit one million players. The winner will receive something "SPECTACULAR." Best of luck, but don't get The Behemoth too distracted with your entry on the company's forum, it has another game to finish.
