Ever stumbled into a weird mashup of mahjong and crime drama? That's Mahjong Cop Ryuu for you—a Japan-only Sega Genesis oddity where you play as a detective who... solves cases by playing mahjong. No, seriously. The story's full of yakuza intrigue, and every breakthrough comes down to winning tile matches. The pixel art's got that gritty '90s anime vibe, and the soundtrack nails the cop drama tension—until someone slams down a winning hand, anyway.

First ten minutes? You're thrown straight into a smoky backroom game while some mobster monologues at you. The mahjong rules are classic riichi style, so if you're not already familiar with Japanese scoring, expect to fumble a bit. But there's something weirdly satisfying about out-bluffing a virtual crime lord when your last tile completes a sneaky pon.

Definitely one of those "only in the '90s" concepts that makes retro hunting fun.
