Picked up Planet Crafter after seeing it featured on PA. Nice relaxing minecraft-esque explorer/builder, with the hook being that as you progress through your tech tree and expand your base you're terraforming the entire planet. Gameplay-wise it's nothing we haven't all seen a few times before, but I think they did a good job of making a world that's fun to explore and giving the player the feeling that they're making a major impact on it.
