It's a great mod. I love it. Especially the latest updates. The new factory designs are perfect fitting. And the idle animations of the flying bots, probing ruins, look good.
Maybe a "boss" would be nice, like a fulgorian stomper. Something like a carrier / gunship could work, with a railgun aiming strait and launching fighters like a strafer.
Explosive biters are on Vulcanus already, and frost ones on Aquilo =)
Different enemies per planet, giving different challenges and fitting to different biomes, do "scratch" the exploring "itch". on the new planets, i, mostly, do not need to move far from the first landing position. I enjoy exploring a world way more than only building the same factory again and bigger.
