Dundee developer Realtime Worlds has revealed a raft of APB statistics as administrators seek a buyer for the embattled studio.
APB has 130,000 registered players, apparently, and the average player plays for four hours a day.
Paying players average $28 per month, "a combination of game time and user to user marketplace trading".
Administrator Paul Dounis said: "These are healthy numbers and reflect positively on APB as a ongoing concern.
"They prove this is a very sticky and enjoyable game, which is shown by the average player daily playtime and an ARPPU (Average Revenue per Paying User) that is highest of any game out there."
Realtime has suffered a torrid time in recent weeks.
It went into administration following lackluster sales of APB, and is now up for sale.
Last week sources revealed that staff were told whether they had lost their job via a PA system announcement, although Eurogamer has since been contacted by an ex-Realtime staff member to refute this claim.
Reports suggest a new studio may arise from the ashes of the developer - one that will ensure social gaming project MyWorld meets its projected spring 2011 launch.
Administrators claimed to have restructured the studio to ensure the game's future, promising a "pipeline" of future updates and game improvements.
