That number has changed because the second time they fucked with the economy, the setup was to find a really hostile planet, find an activated indium deposit, find a strong magnetic field, and set up a farm. I had one that was making me $12b a day.
I had another farm where I cooked circuit boards. Took a little longer but made like $60b a day.
Which was a much more cheese-dick way to make money than salvaging busted ships, because you used to be able to look around for ships, swap them and sell them, basically shade-tree-mechanicing your way to success.
The problem is? They crashed both of these options abruptly rather than tapering them off or whatever so you get the impression that whatever you're doing in one moment won't last until the next one. My wife stopped playing when she couldn't salvage ships any longer.
As far as Farmville goes, Surviving Mars is more fun. No Man's Sky has a real pointlessness problem.
