Evaluation
Sethian launched on November 9, 2016 as a self-contained sci-fi puzzle game centered on mastering a fictional language. The store description presents it as a complete, standalone experience with a defined narrative arc, a handwritten journal and dictionary, and multiple endings. There is no indication of post-launch DLC, expansions, seasonal content, or ongoing updates of any kind — no DLC has ever been listed, and no developer communications reference future content plans. The game was designed and shipped as a finished product.

About this game
Sethian is a sci-fi puzzle game in which you master a fictitious language. An archaeologist in the distant future, you venture to the far-flung planet of Sethian, investigating the mysterious disappearance of the people there centuries ago. An abandoned computer may have the answers you seek, but it only operates in the lost native language. Master their language, unravel their mysteries, and challenge their philosophy.
An Original Language
Unlike in other games, Sethianese is a more earnest attempt at creating a fictitious language, using its own unique grammar and vocabulary rather than simply substituting words and letters one-for-one with English. The game's language borrows elements from Chinese, American Sign Language, and other real world languages, in addition to some features which have no real world counterpart.
Over 100 Handwritten Pages
Assisting you in your investigation are your handwritten journal and dictionary, easing you into the game's bizarre language, providing you with a reliable reference, and introducing you to the literature and lore of the world.
Multiple Endings
Those who comprehend the game's language will find peace, but only those who master its world will truly see the end of Sethian.
