Galactic Civilizations III. I'm about 10 turns away from filling up the Ascension Crystals with a custom civilization focused on research.
The research tree seems endless with many 1-turn tech still left to unlock and I have no idea what to focus on in order to build the Ascension Portal/Gate thing.
But I unlocked the Huge design for ships, so I'm going to try and make one before the time is up.
I spent around 8 hours total on this match, most of it Sunday. I'll probably finish it tomorrow if I have time to play.
