Abstract In order to control the increase in space debris and to actively promote its removal, the activities of space companies are indispensable, and the incentive design for them needs to be properly implemented as a social system However, the current fiat currency system has to rely on a design based on taxation and a system of subsidies, and there have been difficulties in obtaining a realistic solution The authors have proposed a solution using a new digital currency (ADR currency) in the past, but there is another difficulty in that the concept is difficult to spread due to differences with the current monetary system Therefore, in this study, a text-based game simulating the corporate activities of space companies in a society where legal tender and ADR currency coexist was developed as a serious game (a game whose main purpose is not entertainment) using generative AI The method is simple and could be useful for simulating decision-making on various other issues related to space exploration Simulation of economic activities related to space debris using a serious game — 2024-10-29 – p.2/10

ADR Currency token value of ADR token proof of disposal witnessed token vanishes smallest unit B’s contribution C’s contribution years this OD may have caused harm (max. 50 years) token The token represents a liability for the entire space industry, and it pays off its own debt as its face value depreciates Simulation of economic activities related to space debris using a serious game — 2024-10-29 – p.4/10

Serious Games Games whose main purpose is not pure entertainment For example, the main objective may be to solve social problems What about the challenges that are difficult to solve? → We can aim to solve the “how do we let people know it’s a difficult challenge?” challenge Is it different from a simulation? The second purpose is to be entertaining We know that we can let people learn by creating serious RPGs with generative AI cf. K.Saito, et. al. 2023.

Designing the ADR Game with Generative AI Declarative natural language programming (just described the settings) 4 parts Main instructions Stages (Earth, Moon and beyond), turns (quarter years), general descriptions of assets, events and businesses “currency.txt” file Fiat and ADR currencies, taxes and depreciations “items.txt” file Ground stations, launch sites, rocket factories, satellite factories, (debris removal) satellites and debris “events.txt” file Debris outbreaks, collisions, crushing, retirements, strikes, fraud, etc. Simulation of economic activities related to space debris using a serious game — 2024-10-29 – p.6/10

Playing the ADR Game Single player version is available as a GPT https://chatgpt.com/g/g-uKMdRDCBV-adrkemu You should be able to play this in English, too Multiplayer version has been implemented using a fork of GPT Discord Bot developed in Keio AIC Consortium The bot system (we will share the full game prompts with the public at a later date) Multiplayer is recommended as it stimulates dialogue between users and makes it easier to reach the objectives of the game Simulation of economic activities related to space debris using a serious game — 2024-10-29 – p.7/10

Multiplayer Play Example By playing it interactively with several people, we can discuss the problems that arise in the situations this prototype introduces For example, here we dis- cussed a specific issue: when and how to remove debris from other companies Simulation of economic activities related to space debris using a serious game — 2024-10-29 – p.8/10

Demo We explain the log of a test play by the authors Declare initial set of assets Sell and/or buy assets and/or services in the market Hire people Operate satellites Remove debris Simulation of economic activities related to space debris using a serious game — 2024-10-29 – p.9/10

Conclusions and Future Work By experiencing a world with ADR currencies in a multiplayer setting, not only were aspects related to currency addressed, but also situations we may encounter when advancing ADR was prototyped, which sparked discussions We believe it can provide an educational experience for both engineers and business professionals The game itself has become somewhat too difficult, perhaps because it is too closely aligned with reality in some ways, so we aim to further abstract it, making it easier to play while evolving it into a game that also provides hints for solving real-world problems with respect to ADR Simulation of economic activities related to space debris using a serious game — 2024-10-29 – p.10/10
