Adding to the other comment, I feel like you can get a taste for all that by visiting the game’s subreddit. Seeing all the cool things people do and how the community moves the story forward really motivates me to play the game. I guess you could also watch a youtube video to get up to date on the story and different ways to play the game.
It is a great game but you really do need to look stuff up to fully enjoy it, unfortunately. Also, space trucking is only one way to play it.
