Platform: Steam
Price: $7

Sure, a "magical realist adventure game about a secret highway in the caves beneath Kentucky" sounds like it's probably good enough reason to play the wildly IGF nominated Kentucky Route Zero, but then there's the art: beautifully understated in a homespun style, it's kind of like Norman Rockwell by way of Out of This World. Part 1 is on Steam now or you can pick up the whole five part series for $25 to be downloaded as they're released throughout the year.
