I frequently get this question and there’s 2 ways of thinking about this:

1. A significant number of people buy the game just to read it; and that’s a solitaire activity I’ve definitely intended the game to support.

2. I haven’t yet written a solitaire mode but it is something I keep looking at doing. My biggest reservation is that the rules load is already too big and having one person take on that load is genuinely going to be a problem. There’s also not too many places that a single person is going to have an impact in the future - a crew is kind of the minimum group size to do so and I’ve already cheated by halving the crew size from 8 to 4.

Nonetheless, I’m sure people have tried to play solitaire. And I’ve pencilled in a couple of solitaire options for update 5 that’ll be “supported”.

I play solo, and its definitely a 'hard mode' but there's some ways to make it work. The main thing is to give yourself two archetypes. You take the age and ability scores of one, one service history from both, and take all of the skills from both (that your crew quality allows). Duplicate skills take the higher skill level +1. You also start with 1 Glory to make up for the lack of other player's bumps. There's some small niche problems that may arise from playing solo, such as not having the required workers to efficiently build bases at the facility level, so you can either just pretend you have 4 crewmembers when needed, or roll with the punches like I do- which while they tend to make the game harder, you go down avenues not previously thought of. Like in my current game I'm trying to build my first base on the venus aerostat, but since I don't have 4 workers, I'll need emancipated robots since they count as workers. But that requires me to not only emancipate robots- which is a whole game changer- it also encourages me to spec into robots earlier on, as this is literally year 1 of the game., and also get the infrastructure to print them. The whole process takes much longer than a simple Industrialization operation, but its a unique experience that I think is worth the extra time.
