Arcane Saga you have not gotten too attached to it. The game relaunched in the US just over a month ago, and now the game has announced an impending shutdown later this year. Somewhat unusually, the actual shutdown date is September 16th, meaning that the game will be waiting for the final shutdown longer than it was running normally. Netmarble has already closed up the cash shop; players are able to spend any remaining cash shop currency on the company's other titles.
According to the announcement, the game simply wasn't taking in enough money to remain profitable. Arcane Saga was a relaunch of Prius Online, which had already been shut down once before. Our condolences go out to any gamers who had hoped for a long and fruitful future with the game.
