Iliya, Steph, and I played a game of Ad Astra.  I started with a water world, so I set my aim towards the terraformers.  Iliya and Steph were getting pretty good synergies from each other on production and scoring, but I was able to just barely outstrip them by building 4 terraformers, and scoring that card twice.  I won by 14 points, which is a pretty big margin.
