Bring your existing science-fiction character, make open-ended decisions, save and share branching adventures, and see key scenes from your character’s point of view.
Virtual GM Lite is an AI game master for solo science-fiction roleplaying. It presents situations, portrays non-player characters, interprets ordinary-language actions, requests 2d6 rolls when uncertainty matters, and turns the results into consequences and new decisions.
To begin a new game, enter START, answer the setup questions, import or generate a character, then enter BEGIN to launch the adventure.
You do not need a group, a prepared adventure, an API key, custom prompt-writing experience, or a paid ChatGPT subscription.
What Is Virtual GM Lite?
Virtual GM Lite is a solo science-fiction text-adventure game that runs through your ChatGPT account. It uses Frank Succardi’s customized branch of 2d6 science-fiction roleplaying, developed from open-gaming foundations associated with early Mongoose Traveller and Cepheus-style play.
Its customized AI RPG engine also grows from design foundations developed for the full Virtual GM, its larger CyborgPrime-hosted sibling product. Virtual GM Lite focuses that work into an accessible solo-play experience available through an eligible OPS membership.
Virtual GM Lite is an independent CyborgPrime product. It is not an official Traveller product.
What You Can Do
These features make Virtual GM Lite a playable decision-and-consequence system rather than an endless stream of generated prose.
| Capability | Practical Benefit |
|---|---|
| Import a character | Continue with an existing science-fiction character from readable text or PDF information. |
| Generate a character | Start quickly with a character created to your specifications. |
| Save and load | Continue from a portable game-state file outside the original conversation. |
| Share a save | Let a friend branch the adventure from the point where you stopped. |
| Create a snapshot | Render a visual interpretation of the current scene from your character’s point of view. |
| Check character and inventory | Review the current game state with the char and inv commands. |
These tools support the roleplaying rather than replace it. Your decisions remain the center of play.
What You Need to Play
- An eligible OPS membership
- A free or paid ChatGPT account
- A supported web browser
- Two six-sided dice or an online 2d6 roller
A paid ChatGPT subscription is not required. No API key or AI configuration is needed.
Physical dice work well, but you can also use the Google dice roller when you do not have two six-sided dice nearby.
Your First Five Minutes
- Launch Virtual GM Lite from the CyborgPrime Premium Dashboard.
- Enter START.
- Answer the setup questions.
- Import an existing character or ask Virtual GM Lite to generate one.
- Review the active character with char.
- Enter BEGIN to start the adventure.
- Use LOOK if you want the current location described again.
- State your first action in ordinary language.
To restore an existing adventure instead, enter load and provide the Virtual GM Lite save file when requested. Use HELP whenever you need a summary of the available commands.
Import or Generate a Character
Import an Existing Character
You can import character information from a plain-text file, pasted text from a word-processing document or online tool, or a readable PDF character sheet. This includes character PDFs produced by tools such as Traveller RPG Suite.
Clear, text-based files work best. Image-only or heavily formatted PDFs may require copied text or manual corrections.
Upload or paste the information when prompted, then enter char to review how the Virtual GM interpreted it. Check the character’s name, characteristics, skills, equipment, injuries, finances, and other details that matter to play. Correct anything missing or misread before the adventure begins.
Review files before uploading or sharing them, and remove personal information that is not needed for the game.
Generate a Character to Your Specifications
You can also describe the kind of character you want. Useful specifications include career, skills, age, background, personality, goals, equipment, strengths, weaknesses, and complications.
Create a former merchant scout who is skilled at navigation and negotiation, distrusts corporate security, and owns an aging courier ship with maintenance problems.
Review the result with char, request adjustments, and confirm the version you want before entering BEGIN.
How Play Works
Read the current scene, decide what your character says or does, and enter one meaningful action in ordinary language.
- Examine the damaged control panel.
- Ask the guard who ordered the lockdown.
- Move quietly toward the cargo bay.
- Search the office terminal for information about the missing crew.
- Draw my weapon and take cover.
- “What happened here?”
Specific actions usually produce clearer results than vague commands.
Vague:
Search.
Clearer:
Search the desk and computer terminal for information about the missing crew.
Name the goal, object, person, location, or method when it matters. Avoid combining several unrelated actions into one entry.
Your character’s actions, dialogue, priorities, and intent remain under your control. Virtual GM Lite controls the environment, non-player characters, opposition, discoveries, and consequences.
A Complete Play Example
This example shows how Virtual GM Lite moves from scene description to player choice, skill check, dice result, consequence, and a new decision.
1. The Virtual GM Establishes the Scene
The scout cutter Wayfarer’s Wake is grounded in the black marshes of Khepri-9. Elias Kade wakes in the med-bay while emergency lights pulse red and the ship’s computer repeats a damaged warning. From somewhere below deck comes a slow metallic impact: three knocks, a pause, then three more.
The scene gives the player a location, a problem, sensory information, and an immediate reason to act.
2. The Player States a Specific Action
When I get to the doorway, I carefully look forward and aft.
The action is concise but specific. It identifies the character’s position, method, and intended observation.
3. Virtual GM Lite Calls for a Skill Check
The check shows the relevant characteristic, skill, modifiers, difficulty, target, timeframe, and reason for the roll.
The player rolls 2d6 and reports a 9. With the Recon modifier, the final total is 10, producing an effect of +2 against the target of 8.
4. The Result Changes What the Character Knows
The successful check does more than say “you succeed.” It reveals actionable information, increases tension, and returns control to the player with a new question: what do you do?
5. A Snapshot Visualizes the Moment
Using snapshot produces a first-person visual interpretation of the current scene. In this example, the image shows a dark ship passage, an open maintenance ladderwell, blood around the hatch, warning lights, and the character’s weapon in the foreground.
The snapshot reinforces atmosphere and spatial understanding, but the written game state remains authoritative. Treat the image as a visual interpretation rather than a precise tactical map or guaranteed record of every established detail.
Special Commands
Use ordinary language for actions inside the fiction and these commands for setup, navigation, reference, and continuity.
| Command | Function |
|---|---|
| start | Begins a new game and opens the setup questions. |
| begin | Starts the adventure after setup is complete. |
| help | Displays a summary of the available commands. |
| look | Describes the current location again. |
| snapshot | Renders a visual interpretation of the current scene from your character’s point of view. It is not a precise tactical map or guaranteed record of every established detail. |
| save | Creates a portable Virtual GM Lite save file for storage or sharing. |
| load | Restores an adventure from a Virtual GM Lite save file. |
| char | Displays the active character sheet. |
| inv | Displays the active character’s inventory. |
A character source file supplies character information. A Virtual GM Lite save file stores the current adventure state. Keeping those terms separate makes importing and continuing easier.
Dice, Resolution, and Consequences
Virtual GM Lite uses a customized 2d6 science-fiction rules engine. When a roll is needed, use two six-sided dice or the online roller, then enter the result requested in the scene.
Follow the instruction shown by Virtual GM Lite. It will tell you whether to enter the raw dice, a modified total, or another requested result.
- Your character attempts something uncertain and consequential.
- Virtual GM Lite requests a 2d6 roll or other stated procedure.
- You roll and enter the requested result.
- The Virtual GM applies the outcome.
- The changed situation creates the next decision.
A failed roll should not automatically end the adventure. Failure is more useful when it raises a cost, consumes time or resources, reveals danger, changes someone’s reaction, or creates a new problem.
Virtual GM Lite does not claim complete rules automation, perfect interpretation, or compatibility with every science-fiction RPG system. When a procedure seems wrong, clarify it before continuing.
Correct Mistakes Without Rewriting the Adventure
The Virtual GM may occasionally misunderstand an action or confuse an established fact. Correct the relevant point briefly, then return to play.
Captain Varo stayed aboard the ship. Chief Engineer Pell is the missing crew member. I ask the dock supervisor when Pell was last seen.
Correct genuine continuity errors or misread actions. Do not erase a legitimate consequence simply because it is unfavorable.
Save, Share, and Continue
You can continue through the retained ChatGPT conversation or through a portable save file.
Continue From ChatGPT History
- Sign in to the same ChatGPT account.
- Open the retained Virtual GM Lite conversation.
- Continue from the last scene.
Keep the conversation in your history when you intend to return to it. Do not delete it or use a Temporary Chat for an adventure you want to retain.
Continue From a Save File
- Enter save.
- Store the resulting Virtual GM Lite save file on your computer.
- Open Virtual GM Lite later and enter load.
- Provide the save file when requested.
You can share the file with a friend. They can load the saved state and continue from the same point, creating a separate branch of the story.
Use descriptive filenames such as varo-station-before-airlock so you can distinguish branches and return points. Remove unnecessary personal information before sharing files.
Current Limits and Best Fit
Virtual GM Lite may occasionally misunderstand details, require a concise correction, or benefit from a recap during a long conversation. ChatGPT account and usage limits may apply, and retained chats still depend on the user’s account and settings.
A Strong Fit
- Solo RPG and Traveller-style science-fiction players
- Interactive-fiction fans
- Players without a regular group
- Players seeking a low-preparation, text-based adventure
- AI-curious players who do not want to configure an AI system
Less Suitable
- Groups seeking to replace a human game master
- Referees mainly seeking campaign-preparation tools
- Players expecting a graphical video game or complete rules automation
- Users unwilling to use ChatGPT
- Players expecting guaranteed permanent storage or perfect continuity

Virtual GM Lite and the Full Virtual GM
Virtual GM Lite is built from the same underlying design foundations as the full Virtual GM, but the two products have different roles.
| Feature | Virtual GM Lite | Full Virtual GM |
|---|---|---|
| Status | Available now | In development |
| Delivery | Runs through the player’s ChatGPT account | Planned CyborgPrime-hosted system |
| Primary role | Accessible solo science-fiction text adventures | A larger hosted solo-adventure platform |
| Continuation | Retained conversations and portable save files | Hosted capabilities remain roadmap material until released |
Choose Virtual GM Lite for the experience available now. Treat descriptions of the full Virtual GM as development direction rather than released functionality. You can also explore the broader Virtual GM product family.
Experience Behind Virtual GM Lite
Frank Succardi brings more than 40 years of programming and tabletop game-mastering experience to Virtual GM Lite. His work spans tabletop adventures, text games, MMORPG development, 2D science-fiction RPG prototypes, and 3D dungeon-crawl development.
Related work includes The Crucible dungeon crawler, the Realm Crafter User’s Guide, and playable projects including Cosmic Drifter and Hammurabi at CyborgPrime’s itch.io home.
Across those formats, the same design lesson applies: the player needs a clear situation, meaningful agency, and consequences that make the next decision matter.
