Quote from st0lveYou should see some parts of 2, 3 and 4. SH1 is an innocent summer walk compared!
Played parts of 2 and 3, they aren't that scary.Since it just got kinda old when you have seen almost the same stuff in 3 games.
Each game has a few key scary-as-fuck moments; the actual gameplay/combat isn't all that scary. Places like The Mirror Room of SH3 and that electrocution cutscene in SH4 really got to me, but I see where you're coming from: the original SH was quite original and daring, so its impact was undoubtedly greater.
