Monster Hunter Tri has already sucked away over a million hours of gameplay time from users, according to stats from the Nintendo Channel. In just 63 days from release, the monster hunting epic stole a full million hours from users who reported logging in to the game over 330,000 times. The high number isn't necessarily a record breaker (Super Smash Bros. has garnered 100 times that, and players have spent 17 billion hours on Xbox Live), but where Monster Hunter Tri stands out is the per player duration: players of the game have spent an average of 52 hours in the game so far.
By comparison, Super Mario Galaxy 2 has eaten up 1.8 million hours of free time over 710k times, but the average time played there is about 20 hours -- more players, less time each. There are only four games ahead of Monster Hunter Tri in terms of played-per-person time, and all of them have been out for much longer. In other words, monsters aren't the only thing being hunted in this game -- free time had better watch its back as well.
