Grinding Gear Games launched their free-to-play online action RPG Path of Exile earlier last month, and are now reporting some impressive figures: 250,000 players log in to the game each day, while over four million in total have registered to play.However these numbers are not exclusive to just the past month, as Grinding Gear Games launched Path of Exile into open beta back in January, but the statistics are impressive nonetheless and certainly not a common occurrence within the indie game scene. Of course, being able to tap into Steam's daily user base - one which recently surpassed 7 million - helps a bit too.
