Imported from my Backloggery:

While SOMA didn't necessarily blow me away on the first playthrough, due to the unenjoyable monster encounters and well-tread thematic ground, SOMA has stuck with me longer than I really expected it to. Messing with machines and turning knobs was really fun, the amount of depth that is present in the writing, as well as the oppressive and hopeless atmosphere has haunted me for a while. Although the ending was undercut slightly by the post credits scene, the ending was still quite moving.
