All I know is that I love and respect Square Enix a lot compared to how other AAA game dev companies and publishers operate. Square Enix always tries to take risks and make games that none of the other AAA studios like Ubisoft, EA, etc do. Imagine a AAA company making a card game, apart from CD Projekt Red, none of the other AAA studios has made games in that genre, Square Enix has gone and made some of the best card games out there.

include library bio of 4 main characters & final boss, apparently that explains the ending,
guess they ran out of budget.
