To be gained? No. But if you're lucky, once a new moon you will randomly encounter someone else doing their thing. It's pretty cool when it happens, and it felt amazeballs when it happened to me at an Odyssey settlement that we later carpet-bombed together. You can also enjoy getting ganked in Deciat, or at whatever station the current CG is at. But Deciat is a lot more reliable as CGs are full of boring people, so being paired with hostiles is a lot more unlikely.
99.99% of the time, it's like solo. That little .01% is fun when it happens. If you're unlucky and for some reason unable to high-wake, it may turn into a rebuy screen, but ultimately, what else are those credits good for anyhow? I'm at the point where I don't really care much about any progress bar, so whatever.
