I think we can all agree that Silent Hill 2 is the best in the series, and although Konami have never made much of an effort with the PC versions, if you factor in mods and texture/resolution tweaks this is probably the best way to play it these days – even if prices for the (extremely rare) retail copies can be pretty extortionate. It was the first game to really push the idea of horror narratives as subjective, fluid and untrustworthy things, with a story that invites interpretation and a semi-sentient city that warps and shifts itself to fit the damaged psyches of its inhabitants. The confusing cult nonsense of the first and third games was pushed to the backburner for the more personal story of a psychologically damaged widower battling his way through a foggy purgatory populated by zombie-things, dog-things, and whatever the hell Pyramid Head was.
