So I thought this would be a good time to nail it down and re-bought it on GoG. Now there's a new "Aquarius" Edition. They added... fishing to the game

Fishing rods, fish traps and of course fish to catch on various worlds. There is a fair bit of underwater shit in that game (creatures to scan, subs, bases etc.), I guess it fits. I wouldn't care about that, but they also added a fishing skiff vehicle. I might like that on water worlds, for you get "milestones" for scanning planetary creatures. You have to get them all to get the milestone, and some are under water. So I could use my skiff as a platform instead of swimming from the nearest island I can land my ship on. Since it's a platform, the skiff, I'm sure I can operate my hand scanner.
They've got some visuals of it here

Since I have played it all of twice since starting a new game with my GoG edition, I'll just wait until they have this on GoG and install it, then I'll start a new game. I should be able to stabilize on that version then.
