I remember that ghost and yeah it was a bit hilarious and there was another one running with a guy in a wheelchair it sounds creepy but it was not but the game is not scary because of the ghosts (which I admit I don't find them scary either) it's scary because of the ambiance in general, playing a FF with headphones in a dark room is scary, the sound effects and the music it's superb on the FF series side to side with the SH.
I think REs are good as survival horror games but on the scary side not so much at least not for me, even as a kid I didn't find them scary, (not counting one or two jump scares from nemesis or a hunter/licker jumping at you from nowhere )
btw thanks for sharing that novel
gonna post this new here even if its not the right place (don't want to start a new thread)
