Pugmire is a DnD-esque game about uplifted dogs exploring a post-Man world. The dogs (along with other uplifted animals, such as cats, rats, badgers, and lizards) are capable of using tools and language, and they have built their own society upon our ruins (the details of mankind's disappearance are kept intentionally vague). It is a very upbeat and moderately cinematic game: a beacon of optimism in the despair of murderhobos and grand futility of gonzo adventuring. It's post-apocalyptic from our point of view, but to the characters, the Ages of Man are parts of their mythology rather than history, and the remnants of our civilisation are more like holy artefacts than archeological evidence.
