Nishimura Kyoutarou Mystery: Blue Train Satsujin Jiken is one of those old-school Famicom detective games that feels like playing through a pulpy crime novel. You step into the shoes of Kyoutarou Nishimura, a sharp-eyed investigator trying to crack a murder case aboard a fancy blue train—think Agatha Christie but with 8-bit charm.

Right off the bat, you're talking to passengers, picking up clues, and piecing together alibis. The dialogue is all in Japanese, so unless you're fluent, you'll be leaning on guides or trial-and-error. Still, there's something oddly satisfying about the slow burn of flipping through testimonies and watching the story unfold, even if you miss a detail or two.

It's definitely niche, but if you're into retro mystery games, this one's got that classic whodunit vibe down pat.
