999: Nine Hours, Nine Persons, Nine Doors

The game is a murder mystery visual novel with a heavy story focus that requires multiple playthroughs to figure out and involves puzzle rooms used to progress through the story with dialogue choices to be made inbetween them.

The dual-screen, touch-enabled Nintendo DS (2004) became the best-selling handheld of all time, helped by its huge and genre-diverse library. Cartridge-based DS games have held up well physically over 20 years, and complete-in-box copies of the system's biggest sellers (Nintendogs, Pokémon, Mario Kart) remain very accessible for new collectors starting out.
