About LEONIS and Fabi
The freedom to build a different life
Behind LEONIS is Fabi: a nurse, a passionate PC gamer and the mind behind a game world where imagination meets real questions about life.

A personal idea
His idea is a personal one. For many years he has been drawn to games in which decisions make a difference: building something up, understanding how things connect, discovering possibilities and turning a small start into something of your own. He has been shaped above all by the city-building mechanics of Anno, the loving attention to detail of small indie games and the open worlds of the Grand Theft Auto series.
With LEONIS he wants to combine this fascination with his experience of the real world: to create a world in which people can try out different paths through life, from their first income to the opportunities and obligations of great wealth.
I
From competition to a game of his own
For Fabi, gaming was never just an occasional pastime. More than 10,000 hours in Counter-Strike: Global Offensive and his time as a semi-professional player shaped how he sees games. Deciding under pressure, reading a situation and living with the consequences of a decision were all part of competing.
Today that ambition is aimed at a project of his own. With LEONIS, he is particularly interested in how individual features add up to a believable world. What happens after a purchase? What does a place mean when you come back to it? What possibilities does a relationship open up? And how do decisions change when you carry more responsibility?
What he is aiming for is a game whose connections you get to know over time, with details that invite you to explore.
II
An idea born from a personal gap
Fabi had never found a game that convincingly brought his interests together: a believable stock market simulation, economic development, building things up and the freedom to shape a life of your own.
The vision of LEONIS grew out of that gap.
The name stands for the meeting of imagination and reality. Players should be able to picture what their life could look like and try out different paths: making a home, getting ahead at work, investing, travelling, making connections or building something of their own, with decisions that matter beyond the next click.
LEONIS is meant to leave room for different ideas of success. For some it is financial independence. For others it is a beautiful home, a collection, shared experiences or the feeling of having earned something themselves.
III
Understanding money by making decisions
Fabi is involved in the stock market himself. He got started during the Bitcoin boom, when the price reached around €30,000. He also traded leveraged products, had some success with them and followed his own judgement rather than simply going with the crowd.
These experiences are part of the background to LEONIS. Just as important to him is the lesson of how quickly money can disappear again.
With leveraged trading in particular, any potential gains come with substantial risks of loss.
That is why, in the game, he wants economic connections to be something you experience: where does income come from? Which expenses keep coming back? How much does life cost? What is left after a major purchase? And what possibilities open up as you build wealth?
A bank balance tells only part of the story.
What also matters is the commitments behind it, how much money remains available and what risks someone is taking.
IV
Discovering life after school through play
Fabi particularly cares about bringing younger people closer to questions that become very real after school: the first job, a place of your own, recurring bills and handling the first money you have earned yourself.
At the same time, LEONIS is meant to appeal to people of all ages. No prior knowledge should be needed. Anyone who is curious should be able to discover how things connect through their own decisions.
The message behind it is clear: Goals take effort. Money is limited. Decisions have consequences.
At the same time, knowledge, patience and deliberate choices can open up new possibilities.
Whether LEONIS lives up to this educational aim will also depend on what players actually understand and take away from their experiences. For Fabi, this aim is a key driving force behind the development.
V
Power and conflict are part of the vision too
For Fabi, a believable life also includes difficult people, power structures and conflict.
In many games he misses convincing ways of dealing with such situations. What can you do about an unfair boss? How does influence come about? What might a corruption system look like that offers understandable decisions and consequences?
Questions like these are part of his long-term idea of LEONIS. They describe an ambition for the game’s development, not a promise that each of these areas has already been fully built.
Over time, the world is meant to offer more room to understand how things work and to change something yourself.
VI
A solo developer with modern tools
Fabi develops LEONIS on his own and is open about using ChatGPT and Claude as programming tools.
The ideas, the priorities and the sense of how the game should feel come from him. The tools help him translate those ideas into code, investigate problems and keep the project moving forward.
For him, this way of working makes it possible to pursue an extensive game idea of his own as a solo developer. It also means checking results critically and learning from feedback.
VII
A world that grows with its community
Fabi hopes LEONIS will have an active community that enjoys the game and brings in its own ideas: people who discover special details, point out problems and follow the game as it develops.
For him, that also includes a well-organised moderation team: approachable, fair and with clear rules for treating each other with respect.
In the long run, LEONIS is meant to become a place people enjoy coming back to: for their own progress in the game, for new possibilities and for the community that grows there.
At the start
It all starts with a personal vision: to create a world where you can try out the life you would like to lead. With freedom, responsibility and the joy of building something step by step.
