Meant as an introductory RPG for younger children, Young Centurions delivers that to a T and a bit more. Characters are differentiated from mundane people due to their embodiment of an ideal of the 1900s (like in Spirit of the Century, for which this is based). It also delivers a bit of insight into the pulp genre, and with the campaign rating system (rates the campaign similar to how movies are rated), you could easily tweak it to have older characters in scenarios akin to a PG-13 or R rated campaign to fully represent the pulp genre. Furthermore, in my personal opinion, the use of the Fate Accelerated ruleset is far better suited for pulp campaigns than the Fate Core ruleset of Spirit of the Century, and running campaigns in the early 1900s (whether its the 1910s, 1920s, or 1930s) using this ruleset is rewarding, as it is to teach younger children the hobby.
All in all, it is a good RPG for all ages, even though some of the writing is geared toward younger children. Great read, great ruleset, and I will definitely be picking up a physical copy at my FLGS.
