TLDR summary: After saying they would draw a line in 2017, Square Enix (Tabata) is back again announcing that Final Fantasy XV DLC updates will continue into 2018. With a second season pass focused on story that even "ungrateful fans" will have to get for a fee.
Look, no one should have to wait this long just to get a complete story.. I mean this is so damn bad, FFXV needs a second season pass to tell the rest of the story, and you or us the "Ungrateful fans" have to pay for it.
