Not to make this sound like a console issue, but it is a touch headscratching that they would make all nine titles available on the PS4 when they are making KH3 for the Xbox One as well. Not sure what the equiviant of this would be, but I would imagine that if the audience is there on Xbox One, might as well aim for both consoles (although I suppose considering that these were "Sony Focused," it is understandable if they put them all together on just Sony's platform only).
Either way though, I didn't get the chance to grab these yet, so it could be a fun way to pass 2019 in between waiting for upcoming games and KH3 when it drops next year.
