Cosmic Drifter: A Traveller-Inspired Video Game

Cosmic Drifter: A Traveller-Inspired Video Game

Have you ever wanted to play a Traveller-inspired video game? Check out this little sci-fi JRPG video game I'm working on.

What Is This?

This is my sci-fi JRPG proof-of-concept demo for educational and entertainment purposes.

You can follow the development of this game at

You can follow the lore of this game here, at CyborgPrime Games.

Is This A Traveller-Licensed Product?

No, this is just a Traveller-inspired personal project using the Traveller SRD for reference.

If anybody with a Traveller license wants to hire or commission me to work on a real Traveller video game, they are welcome to contact me!

In the meantime, I will endeavor to create a series of video games with a Traveller flavor but ultimately based on my homebrew system.

How Can I Support This Project?

I am happy to donate my time to this project as a teacher of game design and digital arts.

I will endeavor to use free assets and create original assets when practical.

However, there are some expenses associated that I would appreciate some help with if you are able and interested.

Authoring software like RPG Maker, indie artwork for icons and maps, authoring system plugins, and coffee are ongoing expenses that add up.  I would be very grateful to not carry the expense myself.

If you have experience with Kickstart or think this is a project that could benefit from something like that, please reach out to me and give me some advice - I have no idea how to get started or if this project is even suitable.

Thank you in advance for your support and interest!

Standard Characteristics

character sheet with characteristics

Each character is represented by a collection of statistics that represent different physical and mental aspects.

The higher the number, the stronger the character is n that aspect.

Normal human Characteristics max out at 15. 

This maximum can be overcome by various means within the game, such as cybernetic augmentation.

STR (Strength) - Represents physical strength and influences hand-to-hand damage as well as how much the character can push, pull, and lift.

Your character can learn various skills to help them accomplish their goals in the game.

Some skills can be used in combat, some skills can be used outside of combat and some skills can be used both in and out of combat.

Some skills are tested passively behind the scenes and change the story depending on outcomes.

Tech Level

In a star-spanning setting, there will be a variety of planets. 

Some will be inhabited, some will be too hostile to support life.

Planets that are inhabited might be at various stages of technological development.

Tech Level is a gauge of how technologically advanced a society is and dictates what types of items will be commonplace.

Tech Levels:

0 - Primitive, stone age. Simple tools made from wood and stone.

1 - Primitive, bronze age to iron age.

2 - Technology of the middle ages.

3 - Gunpowder and steam power.

4 - Industrial age. The invention of plastics and the radio.

5 - Widespread communications, electrification, and internal combustion engines.

6 - Nuclear fission power, computers.

7 - Routine travel to orbit and the use of communications satellites. Early probing of the solar system.

8 - Space-based stations and habitats. Space travel is more common and advanced probes survey the heavens.

9 - Gravity manipulation is discovered.  Artificial gravity becomes possible.

10 (A) - Jump Space is discovered and JumpDrive developed.

11 (B) - True artificial intelligence and advanced robotics is developed.  Virtual reality is indistinguishable from Real Life.  Memories can be edited.

12 (C) - Weather control and terraforming technology are commonplace.

13 (D) - Advanced weapons systems, such as Battle Dress and routine use of fusion energy.  Basic forcefields.

14 (E) - Fusion weapons become portable.  Advanced medicine makes cloning routine and extends the human lifespan.

15 (F) - Advanced forcefields, life-extension, and neuro-download and replication become possible.

Ancient (Omega) - The Ancient Ones once ruled the galaxy.  Evidence of their existence is scattered throughout the galaxy.  The Ancient Ones disappeared from the galaxy over 100,000 years ago and nobody knows what happened to them.  Their technology cannot be replicated, its power sources are unknown, and most items are unusable by humans or totally misunderstood from their original purpose.


Items can be crafted by players, purchased from vendors, dropped by enemies, given as mission rewards, or even found.

Item icons contain a variety of information at a glance.  Information on each icon includes the Tech Level, Item Type, and Rarity.

item chip

  • Tech Level is noted in the left bottom corner.
  • The Item Type is indicated by the pictogram in the center.
  • The color-coded icon and border indicate the rarity of the item.

In this example, we see the icon for a snub pistol, it is Uncommon and has a Tech Level of 8.

Item Rarity

Items are assigned a rarity level to describe how common or uncommon an item is.

junk item Gray (Junk) - Junk level items, usually worth selling for a few credits. 
common item White (Common) - Common items normally sold commercially, crafted by players, or easily obtained.
uncommon item Green (Uncommon) - Uncommon items can be found at some vendors, crafted by players, or dropped by some enemies.
uncommon item Blue (Rare) - Rare items can be found at some vendors, crafted by players, or dropped by higher-level enemies.
uncommon item Purple (Superior) - Superior items can only be found on missions or crafted by players.
uncommon item Gold (Epic) - Epic items can only be found by defeating Bosses.

Space is a dangerous place.

Pirates prey on merchant ships, and hostile alien lifeforms roam the surfaces of uncharted planets.

You will need a way to defend yourself while exploring the cosmos.


Some weapons take ammo.

Ammo can be used freely between pistols and rifles of the same Tech Level.

For example, TL 6 Ammo works with ALL TL 6 Pistols and Rifles.

Ammo for projectile weapons is indicated by a bullet icon and represents how many shots are left.

Ammo for energy weapons is indicated by a battery icon and represents how many shots are left before the batteries need to be replaced/recharged.


armor stellaris armor shop veyla

Protect yourself from attack with a set of armor.

Armor comes in a variety of styles and is built for a variety of purposes.

Vac suits protect you from the cold vacuum of space, while hostile environment suits allow you to work in environmental extremes; from extreme heat to corrosive atmospheres.


Various devices can help you out in your adventures.

Device use depends on the amount of TEC score a character has.

Scanner: Provide critical information about enemies and entities in your environment.

Pocket Secretary: Tracks missions, allows you to send and receive communications.


It is possible to create your own items in the game.

Weapons, armor, devices, and other things can be created by the player through crafting.

To craft an item, the character needs to know the recipe for creating the item and must have the raw materials (ingredients) in their inventory.

Some items require a fabrication device to be crafted.


Missions are a way to earn money and reputation, as well as to learn the lore of the world. 

Missions also help you earn experience points, gear, and advancement in your Career.

Class Missions

Class missions present opportunities to advance your career by engaging in tasks related to that Career.

Science-based missions advance Scholar careers and combat missions advance military careers, for instance.

Story Missions

Story missions help you learn about the lore of the world; the people, places, and things that make up the game environment and provide backstory. 

Uncover the secrets of the sector by completing Story Missions.


Although the work opportunity can come from anywhere, Patrons are the common source of missions.

Patrons can come in many forms and usually have missions that follow a theme according to the interests of the Patron.


Rumors are a great way to gather leads for possible jobs.

Go to places where people congregate to listen to rumors of interest.


You may not have all the skills you need to accomplish a task.

You may have to hire mercenaries or crew members to accompany you on your missions.

Find crew in places where people looking for work might be.


There are a variety of guilds in the sector.

Some guilds accept any member that applies, other guilds are more exclusive and will check your reputation before they let you join.

Guild benefits range from discounts on certain items to extra skills, special weapons and armor, and even life insurance.


Aside from hungry alien beasts that want to eat them for lunch, a character may encounter a variety of hazards as they explore the cosmos.

Corrosive Atmospheres - Chemical compounds in the atmosphere corrode and degrade regular vac suits.  Unprotected humans would be dead in minutes or seconds.

Radiation - Extreme radiation can severely injure or kill an unprotected human.  Anti-radiation drugs, combat armor, and other items can protect against radiation  and

Vacuum - The vacuum of space is deadly to an unprotected human.  Vac suits are designed to provide life support and limited protection from the effects of vacuum.

Extreme Pressure - Under the sea or on planets with a dense atmosphere, pressures can be extreme.  Hostile environment suits help protect against the crushing pressures present in these environments.

Extreme Gravity - Extreme gravity can crush an unprotected human on the surface of a massive planet.  Powered battle armor and hostile environment suits can provide a measure of protection while allowing the user to remain mobile.


Characters can gain extra bonuses by completing Achievements throughout the game. 


Thank You For Your Support!

I think this could be a very fun project and I am eager to continue past the development I have already done. 

The starting area, Admin Office, Bar, Weapon & Armor shop, the electronics store, and the mine head are all functioning.  You can purchase armor, weapons, and gear.  You can go into the mines and fight mine worms.  SOMe mine worms drop raw crystal which can be sold for Credits.

I thank you for your interest and support - even if it's just simple encouragement!
