This reminds me of the situation DOA5 and DOA6. A sequel so unnecessary releasing near the end of PS4 and XBONE lifecycle, Visually similar to DOA5 and only adding 3 new fighters. It almost seems like it could had been another addition to DOA5. But being a "new" game meant none of the DOA5 DLC would carry over. I've seen other games carry over old DLC. One Piece Pirate Warriors carried DLC over to 3.
