Getting started
RR_genre: A primer on the genre. Pulp science fiction was written a hundred years ago. The culture of the people who read and wrote it was significantly different from the people today.
RR_Role_playing_101: An introduction to role-playing and role-playing games for beginners.
Lists
RR_Name_list: A genre-compatible list of character names. Using it is optional.
RR_Ref_basic_equipment: A copy of the basic equipment list in the rules. It is small and has most of what you need.
RR_Equipment_list: This is the full equipment list. It features expensive name-brand equipment that is better than the stuff in the basic equipment list.
RR_Skill_list: All the skills in the rules & character creation reference, and many more besides. Includes a more detailed description than in the rules.
More background
RR_Service_orgs: Background on service organizations like the Space Cadets, Space Rangers, and other service organizations.
RR_Ref_monsters: A list of monsters and bad guys from the rules.
RR_Alien_details: Some aliens need more detailed information than the 1 line description in the rules. The rules are really short. Here is a lot more information about some of the aliens.
RR_Space_ships: Background on space ships in Roaring Rockets.
Charts
RR_Ref_combat: The combat reference sheet is all the charts & tables you need. One page is for character combat and the other is for vehicle combat. It is handy if printed up as a two-sided sheet. Some players want their own copy, some don't. The vehicle combat sheet is somewhat spacecraft-centric, but good for any type of vehicle.
