Koroshi no Dress

Best friend's fiancé is found dead and naked at the park's toilet. Hero starts an investigation, but then the second murder occurs and his girlfriend disappears mysteriously.

It' suspense mystery from the start since we don't really understand what's going on or who is the killer (but naming the game "killer dress" helps with guessing). It can hardly be called an eroge, but the adult atmosphere is everywhere including many gore scenes. It's a breakthrough game that broke the trend of games being treated as erotic cg collection. This is a game that carries away with the story alone and just couple of erotic cg thrown for the story's sake. System is command selection with a shortlist of commands to select from - very convenient to use. The story is basically a single road, but with good and bad end branching close to the finale. Another rather new feature is the ability to name the hero. This game is a paragon for all the future horror mystery scenario games to come.
