The Pixel Remasters of early Final Fantasy games have all removed opening credits (presumably to avoid confusion about who worked on the original and the remasters), so this appears to be an intentional choice.
Final Fantasy 6 Pixel Remaster includes a bizarre omission, adapting the lengthy original opening credits sequence – but leaving off the actual credits themselves.
The recent Pixel Remasters of Final Fantasy have come under fire for a few unpopular changes to the original games, but this might be the strangest so far.
The opening of FF6 Pixel Remaster doesn’t have the actual credits show up in the horizon so you just… walk.
