FIST lives in a very difficult to manage sweet spot between what makes OSR style games appealing and what makes narrative-heavy indie games fun, accessible, and freeing. With an easy to pick-up and hyper-lean ruleset, it gives you a treasure-trove of gameplay and storytelling that laser focuses on its genre.
Creating new characters is always a blast because there are so many options that mix and entwine in strange and delightful ways. FIST does that thing I love with its character generation where you get pieces of story to fit together - but also some clear mechanical things that your agent DOES.
You will read FIST and think "Oh, this is pretty good."
You will play FIST and think "Oh wait oh my God why did I sleep on this it is FANTASTIC!"
