Ironsworn Starforged; I remember seeing the cover of Ironsworn , I think at a Dragonmeet event, but it was the prospect of a Sci-Fi based experience in solo rpg / journalling which grabbed my attention and thanks Modiphius picked it up last year.
In terms of creating a narrative experience the system provides a level of character creation which defines the backstory for the universe, society and character you plan to play. The prospect of your narrative options being answered in many lookup tables ( referred to as Oracles ) , as well as your own choice in pulling from narrative ideas of other SciFi tales. The system is well supported both online and in communities with a surprisingly effective web app which can handle not only your world building but the character management and adventures; more on that you can discover over on Stargazer.
