Silent Hill was created by a team called Team Silent. They were responsible for Silent Hills 1, 2, 3 and 4 so at the very least you should play those, they're all cut from the same cloth. The rest would all be optional, but I'd recommend you try Shattered Memories as well, it's the most unique out of the western games. Downpour is... not great, and the hardest one to play nowadays (stuck on consoles, never got a port). Still, you've got a ton of good games ahead of you, so enjoy

Oh btw, which ending did you get? You might wanna go back and check the other endings depending on that, especially when it comes to a certain future title
