Azusa 999
About
Azusa 999 is an RPG Maker adventure game (à la Corpse Party or To the Moon) developed in 1997 for the classic Japanese PC-98 personal computer. It's a heavy emotional story about suicide and an otherworldly train… among other things. It's quite unlike anything else – a flawed diamond, forgotten by time – which is why I decided to translate it to English over two decades after its original release!
For ease of use, the game comes bundled with a pre-configured PC-98 emulator – just run the program, and you're off! If you're on Mac or Linux, or if you want the full 1997 experience, you can set up a PC-98 emulator (like Neko Project II) and plug in one of the disk images offered.
The game has an immensely interesting backstory – it was created in a particular niche of Japanese indie game history, which has barely if at all been covered in English. To learn about it, read the translation's foreword, written by yours truly!
