It's by Nexon anyway. If you don't play it you probably dodged a bullet. Their games are extremely P2W and they literally pioneered the earn in-game currency that you can only use to trial weapons and characters method of wealth extraction. It's been so long since I've played one of their games, but that form of microtransaction has always stuck with me as a "if I see it, I'm immediately deleting your game" approach to gaming.
