i searched and searched and i couldnt find any posts on the subject, but, having just played the 2cnd and 3rd installments in the SH series, and i found two very striking parralels between the two games.
1: some of the people in silent hill worships a deity which has powers to put shape to our deepest fears and nightmares, i think this is a direct refference to the deity resting beneath the yucatan pyramid in PiD.
2: a monster in the 3rd installment called "Numb Body". here's the wiki description: "Relatively featureless, bipedal creature; resembles a headless, featherless, wingless chicken. Said to resemble a fetus. Comes in two sizes. Called numb bodies due to the way they walk; stumbling. Make eerie moaning sounds when alive. Have a single, enormous eyeball as a head. Seldom found alone."
heres a pic of a numb body: http://missy.silenthillforum.co.uk/sh3presskit/numb_body_01.jpg
see the "headless" resemblance?
am i going nuts slow as a reaction to playing too much SH or is there something to it?
