I agree. The scariest game is Quake 1. It's so completely and utterly random that you had no idea whatsoever what to expect next. Even with God Mode enabled, -blam!- scared the -blam!- out of you. You would walking down an eerily empty corridor with no sounds. Then, suddenly your character starts randomly grunting, then, BAM!!!! Out of nowhere, 8 Night Shamblers teleport around you and are roaring at you, and you're all like "eh, er, ere" and it makes you jump out of your skin, cos, -blam!- I wasn't expecting that mother -blam!- -blam!-... Yeah old games are definitely scarier, it's less so but still so in Doom 1 and especially Doom 2. Newer games swapped that out for a failed attempt at realism which is inferior to the insanity of 90's games with inter-dimensional hell-demons like what the -blam!-?
Yeah, 90's games are definitely scarier than modern games... :/
