As the title says, this was my first time doing a solo RPG. Such a cool experience, being able to take on the role of both the player and the GM.
This game in particular was a great place for me to start, as the subject-matter itself elicits a very "project hail mary" or "the martian" vibe.
Basically "you're alone. you have limited resources. outlook not so good. But we're still going to do it."
Success in this game really captures the "I just grew a plant on mars" feeling.
This game requires that you feel comfortable with ambiguity and making it up as you go. As I said before, you're the player and the GM. You can decide the right balance of fun and fair for you.
This game invites you to create amazing stories with rules that are descriptive enough to guide you while still keeping you fully in control of whatever story it is that you want to create.
Do yourself a favor and give this game a go. Oh and this book is small enough to fit in any travel bag. Pic attached of me playing this poolside while on vacation in Greece
