Nishimura Kyoutarou Mystery: Blue Train Satsujin Jiken is a quintessential example of the "travel mystery" subgenre that dominated the Japanese Famicom adventure scene in the late 1980s. Based on the prolific works of novelist Kyotaro Nishimura, the game puts players in the shoes of Inspector Totsugawa as he investigates a gruesome homicide aboard the iconic "Blue Train" sleeper express. The narrative is the driving force here, leveraging the suspense of a confined space and a ticking clock, requiring players to meticulously analyze passenger lists and alibis to narrow down a list of suspects.
The gameplay follows the standard menu-driven interface common to 8-bit adventure titles like Portopia Renzoku Satsujin Jiken. Players navigate through various train cars and station platforms using commands such as "Look," "Talk," and "Investigate." While the visuals are functional, capturing the cramped, rhythmic atmosphere of Japanese rail travel, the game relies heavily on its script. This makes it a daunting prospect for non-Japanese speakers, as progression is strictly tied to triggers found within specific dialogue branches and the discovery of items that contradict suspect testimonies.
While the pacing may feel glacial by modern standards, the game successfully captures the "whodunit" tension of its source material. It rewards patience and logical deduction, though it occasionally falls into the trap of pixel-hunting or requiring an exact sequence of commands to move the plot forward. For fans of retro detective fiction, it serves as a fascinating cultural time capsule of Japan's obsession with railway-based noir. However, without a fan translation or high-level linguistic skill, the intricate web of lies and timetable-based puzzles remains largely inaccessible to the western audience.
