Wii wish you a Merry Christmas

[Weltall]

Because the timeline established by the four games in the series demands that it is occupied.

For instance, the second game takes place ten years after the first game, yet three years before Silent Hill 2, the protagonist and his wife are in town on vacation. The protagonist of Silent Hill 4 remarks, before things go wrong, that he has gone there and enjoyed himself, though at the time he is 29 years old, and the fourth game takes place 21 years after the first. In fact, when characters in the later games mention the town, they sometimes say that strange things happen there, but none have ever made a point to mention that the town is a hellish landscape worse than any man's feverish nightmares.
