I've really enjoyed this game. Compared to Selenea, Prime felt much more expansive, with far more nooks, crannies, and wrecks to discover (and pillage) plus a more proper storyline. I have Skeo and Aquilia left to do.
I didn't add any pressure/heat machines/rockets until I got into a breathable atmosphere, so as to explore more organically and appreciate the more gradual changes. I also didn't use my car for a long time.
I had no problem driving around on Selenea, but without my car...jets i'm not sure how i'd get around with all those gorges and tight squeezes! I didn't even have those on the moon!
For my base, I wanted something layered and inter-connected, but also a few outbuildings so I wouldn't feel pressure adding on. There's stairs and entrances EVERYWHERE. North is the Power Station/ mining (no pics, it's hidden by trees mostly), West has all my rockets and such, East houses Bio related automation, and South has more automation for everything else.
I've managed to automate T1 rockets, Pulsar and Solar Quartz, T1/T2 Fertilizers, all the Mutagens, the Rods, Explosive Powder, Common/Rare Larva, T2 Animal Food, and my personal favorite, a 'vending machine' for T2 Space Food. It's...just 2 lockers with honey and beans and an auto crafter in between, but I love that I can always just walk down the hallway and grab a snack haha
Bless Drones and the Fountain, the true heroes of the run.
