I started with two home planets on and X type map (120). I had the central planet bottleneck hard, so I could fight off exo galactic spawns relatively consistently. I was playing 7.6/7.6 tag teamers, with Hard Golems, Hard Spirecraft, Fallen Spire, and Zenith Traders. There weren't many progress reducers in the map (no super terminal), so progress was getting kinda out of hand.
I play on 10+ speed the whole time, so that's why it was a high game time.
