I got it on Switch myself, but it feels more at home there. Not to mention it's not that graphically intensive of a game being a 3DS remaster which I also enjoyed. Also not having to install it, even if the file size is small. Trophies are fun and all, but not enough to get me to buy it.
That said, I thought all new games on PS4 required them now, so I'm tagging this for curiosity sake.
