Solo Oracle for Spacer: Interstellar Roleplaying in the Far Future

unknown Soviet-era artist

I started working on a solo guide for Mongoose 2nd edition of Traveller to release under the TAS on DrivethruRPG but since Spacer being released, I have pivoted to focusing on making a solo guide for Spacer instead which could be used as a generic oracle for Traveller-adjacent games. The following is an oracle system i've been messing around with for Spacer based on the Oracle found in my Old School Revival Solo Role-playing Guide. I refer to the oracle as the "Artificial Referee Computer" or ARC as stupid sounding future term since I feel oracle is to "woo-woo" sounding for the content. 

The following is a sample from Spacing Solo: Solitaire Roleplaying In The Far Future

 Artificial Referee Computer (ARC)

The Artificial Referee Computer (ARC): When you need to discern information in the game, you can “ask” the artificial referee computer questions to determine a result. These questions are categorized into either Simple Questions or Complex Questions.


Simple Questions: Simple Questions represent Yes or No questions that the traveler might have. Roll 2D and consult the following table to determine the simple question answer. 

  • Asymmetrical results: Add asymmetrical results together as normal to determine an answer. Examples of asymmetrical results are 1,5 or 3,4 etc.

  • Double Results: If double dice results occur, they will add a narrative effect to the answer. Consult the table below

2D results

Answer

6,6

Yes, and

total of 8+

yes

4,4 or 5,5

yes, but

2,2 or 3,3

no, but

total of 7 or less

No

1,1

No, and

When interacting with an NPC or performing a task, the solo spacer should apply any DM that might provide a situational positive or negative effect. 

  • Example of NPC interaction: Asking an NPC to do a task that is at odds with their drive, interests, or ability would apply a negative DM while asking them to do something that is along the lines of their drive, interests, or ability with apply a positive DM

  • Example of Environmental Interaction: Interacting with an environment or NPC under restrictions, stress, oppressive circumstances, or some other burden that would hinder the solo spacer would apply -1 DM per circumstance, while being in advantageous circumstances with regards to a lack or restrictions or any supportive situation would apply +1 DM per circumstance.


If either the “…And” or “…But” result allows for a more open response or if the traveller needs some additional insight, they can choose or roll 1D on the Complex Questions table to determine what column they roll a 2D on to provide some result to help continue the narrative.


Complex Questions: A complex question is a situational question to give purpose for answers to provide narrative descriptions or progression of a campaign objective. These questions are framed as Who, What, Where, When, Why, or How questions. The following table can be used to generate rumors, jobs, motives, etc. as well by rolling on each column and combining it into a narrative.

**When: If generating a recent event, roll 1D+6 on this column instead. If generating an very old event, roll D3. Ancient events can be determined by rolling 1D to represent centuries past


Distance Questions: If the solo traveller asks the ARC a question regarding how far away a person/place/thing is, consult the following table.

  • Any possible location: Roll 1D 

  • Planetside Location: Roll D3

  • Galactic location: Roll D3+3
