Okay, so I finished DarkStar One, got "thanked" and turned my back on all the friends I gathered, with seemingly no way to contact them again.

Now - after everything is done - I got the final Ship Upgrade, and the 100 Artifact Upgrade too. Now i can go everywhere in the galaxy at a blink to do... what?
They maxed my money, so earning some is of no use, besides what should I buy with it?
There are only repetetive missions laft, and all in all the galaxy no feels lifeless.

Is there anything else interesting to do, or just hit the quit button and set it to completed in GoG Galaxy?
