We played Hearts Blazing on Saturday: http://www.gamesbyplaydate.com/hearts-blazing/
It seemed a little woolly around the edges but I would certainly like to give it another go.
Our story was about a team of interplanetary troubleshooters zipping around the solar system at exactly the speed of light, solving issues relating to inter-planet conflict and/or the “Bridger” alien refugee population. Some different aliens (or were they?) also showed up and crashed our space station into the sun.
