It literally is a ghost town. Barely anyone is playing and I doubt the upkeep costs less than what Patron whales are throwing at them.
They were never getting 3 expansions worth of progression done in a year. They never should have made that statement. And even if the server had stayed somewhat popular there would have still been a mass exodus when it got to SFP. I mean who the hell wants to pay a monthly sub to a version of the game that they can just play for free? And even then would you really want to play SFP when it has barely anything to do?
Gamigo sadly have to pick up the mess Trion made. Which is a tall order because Gamigo themselves didn't exactly have anything hugely popular until they got hold of Trove. And even Trove has been on a heavy decline in terms of active users.
