I also watched these 20 planetary wonders, it may have been magical, but it wasn’t that bad.
I put down a rocket fortress right away, developed the remnant MK1 engine, and then sent my only spy for planet info. As the Toluans and the Shinari / Godans became involved in the fight, I stood next to the newly occupied planet and, just before the machine-gun fort was built, I hit it. That’s how I got the godans’ planet from the toluens. I was fortunate enough to go after the Shinari’s planet and buy a tracked tank through the commercial center so they could not be repatriated until the rocket fort was built.
Then I started to develop space power. I had a corvette relatively soon, and an advanced space base was added to one of my planets. For a while, I swallowed the weaker planets with my one-eyed corvette, while the enemies killed themselves with the space base around the defenseless planet. When I’m done with tank upgrades, I can come on heavier planets. Space cannon 2nd was a bit heavy, but I made two more corvettes and it was gone. Finally, I subdued the universe with 3 corvettes and 6 megatanks. I replenished it once when one eye was sabotaging my heart and I didn’t feel like sitting down until the next.
