Lmao - except on that blog the first thing that i read was...
"The protagonist enters a seemingly empty room, starts looking around when suddenly a strange sound is heard from outside. Something is about to enter and it's time to hide. At this point the game removes the player's control and a cut-scene is started showing how the protagonist hides and just barely manages to remain unseen by the approaching monster."
This is not done by Amnesia like that - but instead they force the character to lay on the floor, blur vision, make him shake (which removes control and visibility) - In fact Amnesia has cutscenes, without a scene - but they still make cuts - Force your view on things, force your stance to crouch/lie, forbid looking at enemies through actually making you go insane if you do etc.
If some of the players insist on walking up to the man seen butchering his victims then just put them up against him in an unwinnable fight. Next time they should be a lot more careful...
And thats just plain bad game design. In HL2 Raveholm, a level many i know regard as the creepiest level in a game ever (and even after many playthroughs), there is not a SINGLE unwinnable fight.
The rest of that blog post is equally misguided, HL2 combat is fun, yet Ravenholm (and the many desolate zombie infested locations) are still creepy. Dead Space combat is fun, and.. particularly in conjunction with the great audio (thinking of the lullaby singing and other stuff ;p) is just plain mind-wrecking. Was it true Horror? No, it was Action that was Creepy at times, but it sure as hell was a blast to play.
Those Horror games like Penumbra remove too much "fun" from the gameplay. Making them more like work and less like a game. Like removing a minimap , limiting light supply etc.
