Ah okay, it makes sense now. Perhaps that ex-taxinaut (moon dog was his name?) when he mentions Starports he could say "But do remember not to get confused with Spaceports. Starports are found in a system and Spaceports planetside.")
I wonder if having a Codex for the player would be an idea. The ingame tool tips are still useful but the more complex stuff can go over a new players head or too much information to absorb. I have been making notes. I like the depth to the game so in no way do i suggest streamlining that. I wonder if you have a codex that also has a search function, player types in keyword and information displays in the popup-codex. Even if you start with copy and paste the tutorial info already created you get when visiting new places like a motel or home for sale site for first time you get some conversational tips and some other concepts could just be a short paragraph for now. Being able to type a keyword would be faster than clicking on hyperlinks within the Codex, although you still might decide having a Contents landing page for the Codex, which would be good for new players whom do not know what to search for and want to read an overview of how things work.
This would be handy for players who might take a long break from the game and wish to return and need to remind themselves key gameplay points. For example i could type Armor and there could be 2 hyperlinks Personal Armor and Ship Armor. Also having a back and forward arrows on Codex pages like a web-browser could be handy as well, so we could go back and read about the other type of armor. I understand that would be a lot of work. Alternative is a browser based Codex or type of wiki where the community can enter in information or make changes to it when things are re-worked. Also a browser version instead could be handy for players to have it on their second monitor while they play, pause game and then search for something on the web Codex.
But i understand if you would prefer to do a Codex like this last once all the systems are locked and done, as you might make changes and that would mean re-writes of the Codex.
I know you have a couple of tutorial videos but i found it hard to follow as i am hard of hearing.
