About this game
A young man named Yukiya goes on a yacht travel together with a few friends.
Suddenly, a terrible storm comes out of nowhere: Yukiya is washed out on the shore.

He regains consciousness, but not memories of recent events.
Realizing that he is on an island, he begins to explore it and reaches a big mansion.
To his surprise, his friends are already there; apparently, they have all been invited.
Thinking that the worst is behind, Yukiya goes to sleep.
But the next day, the young and beautiful owner of the mansion, Chiori Nakamura, is found dead in a locked room.
One of Yukiya's companions reveals herself as the famous detective Edogawa Ranko (perhaps Conan's older sister; definitely a reference to the Japanese crime novel author Edogawa Ranpo).
Under her guidance, the group decides to investigate the murder, but it turns out that the mansion is cut off the rest of the world.
They are stuck on the island, and one of them might be a murderer...
Yakata: Nightmare Project is an RPG with detective/mystery thematics rarely seen in games of its genre.
Unlike most RPGs, it is set in an isolated environment; much of the gameplay is dedicated to exploration of the huge mansion and its surrounding, with conversation and event-triggering reminiscent of Japanese adventure games.
The game is done in 3D, the exploration process featuring third-person perspective movement with automatically adjusted camera angles.
It is also possible to physically move on the island map (also in 3D), accessing locations displayed on it.
The actual RPG system is quite simple, with traditional random enemy encounters and turn-based mechanics.
Battles take place on separate isometric screens.
The combat distinguishes itself from other representatives of the genre by having offensive and defensive turns.
During a defensive turn, the player can choose to defend, reducing the damage, or move to another place on the battle screen, hoping to avoid the attack.

About PlayStation
The original PlayStation (1994) brought CD-based gaming and 3D graphics to the mainstream, ending Nintendo's console dominance of the previous two generations. It's now firmly in "retro collecting" territory: original jewel cases with intact manuals command a real premium over disc-only copies, and several RPGs from its later years (when Sony deliberately courted the genre) are among the most expensive commonly-collected games from the era.
Gamevaro tracks Yakata: Nightmare Project for PlayStation with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Yakata: Nightmare Project to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This PS1 release dates back to 1998.

Rarity & condition
Only a handful of market sales have been tracked for Yakata: Nightmare Project, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common PlayStation titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
