VEILOFTEARSDROWN'S PROFILE

I was introduced to Yume Nikki last year and played it.
Loved it by the way! I then discovered there was an entire genre of these games.
IB, OFF, LISA, Mad Father, Etc.
I know Corpse Party came out in 1996 and Palette came out in 2001 or even 2000?
Corpse Party was the oldest I could find and have researched everywhere for games even older than Corpse Party in this genre and found nothing so far...
Is there any RPG Maker Horror Games that predate 1996?
I’m just curious to know the origin of this genre.
