I enjoy silent hill as a violent exposure-therapy or whatever it's become since SH2 but I would love it's weird and confusing nature to be explored in a way that doesn't involve the town projecting from the minds of the emotionally troubled. The series has roots in a weird cult story that borders on nonsense and i'd like that more just as much as i want more silent hill games about sad confused people with repressed emotions.
You know what, I want a silent hill game fully based on some specific kind of occultism or demonology.
Make malphas a boss fight, add demon summoning mechanics with risk and reward, stuff like that.
Make the main character not a murderer with repressed thoughts showing up in town.
