The Stanley Parable
The Stanley Parable is a really interesting short game available on Steam. It is a first-person exploration that plays with the idea of player agency and the concept of free will as it is implemented in computer games. The new version is an expansion of the original free Half-Life mod, and contains all new art and music, and brilliant honey-voiced British narration by a guy I wish would read me a story every night before falling asleep. With all the meta-commentary and magical realism, it gives off very strong Hitchhiker's Guide to the Galaxy vibes, with a dash of Portal . For me, this is vibe heaven.
