I am getting Silent Hill.
Until Dawn has VERY limited gameplay. It is like watching an interactive movie. Once you've seen it all, are you going to pay £60 to play the exact same thing again but a little prettier than before? Especially when the Until Dawn is one of those games that people remember looking better than it was when it launched, probably due to the use of actors. Everyone looks like their real life counterparts so until you see the remake running side by side with the original you don't really notice the improvements.
SH2 is a full remake, different gameplay style than the original, retains the story and themes but we're talking a PS2 game remade on PS5.
