I had one previous space-age run that stopped a bit into Gelba. If im honest I really didn't care for the spoilage mechanics. Finally getting to the point in current run that planet explorations on the horizon. Want to try something different. Please recommend me a good planet to try next without spoilers (or spoilage).
There's no wrong answer. Go with whatever sounds most exciting. Though I'd suggest doing Gleba last for your first run as it can require more babysitting than the others.
