YIIK: A Postmodern RPG is an indie role-playing video game by American developer Ackk Studios for Microsoft Windows, MacOS, PlayStation 4, and Nintendo Switch. The game was released on January 17, 2019. It received mixed reviews from critics. The game is a colorful 3D Japanese-style RPG. It is set in the 1990s and is based around a mystery in a small town. There are eight characters who are message board friends. They work together to investigate the mystery around a viral video star called Semi Pak, who goes missing in a supernatural event. The player can control the characters in turn-based battles where normal everyday objects are used as weapons. The combat consists of turn-based moves with timing-based actions which can increase the damage of an attack. There are six dungeons to explore which include battles, puzzles which have to be solved and traps that have to be avoided. There are approximately twenty five hours of gameplay. The game is built on the Unity game engine. It began development in 2013, with brothers Andrew and Brian Allanson creating a fully-featured prototype in 52 days for showcase at PAX East 2013. After seeing the game in action at the event, publisher Ysbryd Games entered an agreement to publish YIIK: A Postmodern RPG. Around this time, the Allansons' mother was diagnosed with cancer, which would later result in her death. This caused the team to rework parts of the game's plot, making an effort to "[have] a more 'humanistic' perspective" and "sand down some of the game’s more cynical edges." By the end of this period, nearly a quarter of the game had been remade, including a slight change of the game's ending. A demo was released in June 2016 on Microsoft Windows and MacOS. YIIK: A Postmodern RPG received "mixed or average reviews" on all versions according to review aggregator Metacritic. The game was also criticized for referencing the death of Elisa Lam.
