What is Sethian?
In this sci-fi puzzle game, you are an archaeologist investigating a distant planet whose inhabitants vanished centuries ago. You consult a journal and dictionary to interpret an abandoned computer's replies and construct questions in a language with its own grammar and vocabulary. The investigation has multiple endings.
For you if...
- +you enjoy applying grammatical rules rather than simply decoding symbols
Not for you if...
- −you want open-ended dialogue rather than a prescribed question sequence

Players praise the language-learning concept and the story's themes. The most common complaints concern the computer's limited responses and insistence on exact phrasing, which players say makes experimentation frustrating.
