Yakata - Nightmare Project (1998, Playstation)

Yakata - Nightmare Project (yakata is Japanese for "mansion") is an RPG with some adventure elements. It was developed by Chime and published by ASK Kodansha. The game was only released in Japan.

The game's protagonist is a young man called Yukiya (you can rename him, tough) who gets summoned to a mansion located on an island. While crossing the see on a boat, a storm rises and a giant wave drags him off-board. He awakens at the coast of the island. Unfortunately, he has lost his memory, probably due to a hit on the head. Only the remains of his invitation letter give his name and the place he wanted to go. Upon arriving at the mansion, three other people, who were also invited, have arrived. Their host is a young woman who is the daughter of a famous architect. Her father has also built the mansion. The reason why Yukiya and the others were summoned turns out to be the fact all the buildings by the host's father absorb and amplify nightmares. The host says that everyone invited has a special power and she wants everyone to stay a night at the mansion. However, the next morning, things take a dramatic turn...
