Picture a game of Terra Mystica. You are looking at a piece of land suitable for expansion, but the player next to you builds there first.
Your route is squeezed narrower. But it is not that simple: being close to others sometimes brings the benefits you need. That neighbor who makes you frown may be exactly the person you cannot do without in your next plan.
So you recalculate, switch to another path, and start imagining what your faction will grow into on this map.
Games like this make it easy to remember their massive rules, but there is another question worth asking: why, after the session ends, do we still want to switch to another faction and try again?
Today's subject is Helge Ostertag. Terra Mystica and Gaia Project were designed by him together with Jens Drögemüller; Age of Innovation, on the same creative soil, pushes combinations and variation further forward.
His story is one to tell slowly. Because before the finished game reached its box, there was a prototype that was put in a drawer and taken out again and again over many years.
1. A world put back in the drawer
In a 2016 interview with him, Helge traced the origins of Terra Mystica back to 1996. He and his brother Anselm had made a strategy game provisionally titled Gorod, which already contained ideas of different factions, terrain, and terraforming the land.
In 1997, the prototype was tested by Hans im Glück but was not selected. Later he continued revising it alone; structures such as faction abilities, buildings, and income were gradually added. After attending a prototype event in 2010, he met Uwe Rosenberg, who appreciated the game. The intensive testing that followed involved Frank Heeren and Jens, and Jens also became a co-author.
These are experiences the interviews can support. As for how sad that rejection made him, or whether he ever wanted to give up entirely, there is no need for us to fill that in on his behalf.
Just putting these years together is already weighty enough.
The idea that appeared in 1996 did not immediately become the finished product players saw in 2012. In between lay many reopenings and reworkings, and also the judgments that came when other people entered the project.
What I read from this process is not the guarantee that "persistence always leads to success," but a more concrete creative situation: some prototypes are worth keeping, but keeping them does not mean protecting them unchanged.
You have to allow it to grow new structures, and you also have to allow collaborators to see problems you have long been used to and therefore no longer notice. A long development is not copying the same answer many times over; it is more like constantly checking whether the thing that first attracted you is actually being expressed by the rules now.
2. You cannot be too far from others, nor only focus on being close
In a 2012 interview before the game's release, publisher Frank Heeren described Terra Mystica in a very clear way: players each develop their faction and terraform terrain, while proximity to other players brings both restrictions and benefits.
This relationship is a key to understanding the game.
Suppose you only think about spreading all your buildings onto empty land—you may miss the value of proximity; but if you only think about sticking close to others, your own future room to grow may become smaller and smaller.
So "we are on the same map" is no longer just a seating arrangement. What others have built and where they choose to develop become a situation you must read carefully.
The contest here is not necessarily expressed through armies clashing. The buildings themselves, the space itself, and the timing of when benefits occur are enough to make relationships tense.
Feuerland's official introduction also emphasizes that building and upgrading bring sustained income, and that the abilities of different factions are an important part of the path to victory.
I think this gives every build on the table a double meaning: you are both occupying a place and shaping what you will be able to do next. The map in front of you and the state of your own development are always pulling on each other.
This is my interpretation of the game’s mechanisms, not a standard answer Helge gave to players. But it can explain a familiar experience: the same act of putting down a building sometimes feels like expansion, sometimes like unlocking, and sometimes suddenly makes you realize you have blocked off your own future.
A seemingly quiet building action thus carries a very long echo.
3. After going into space, old questions must be answered anew
Gaia Project was still designed by Helge and Jens together. In a 2017 interview with him, Helge explicitly described it as a sci-fi construction strategy game without combat.
It is not a matter of swapping Terra Mystica's trees for spaceships and calling the migration complete. Modular sectors, the research board, and a tech configuration that changes every game make players understand their relationship with the map anew.
He also talked about how, in space, the distances between colonizable planets change the methods of expansion; the coordination between faction abilities and research directions also needs to be considered together.
This makes me think of a question that is hard to avoid when designing a sequel: which part of the old work do players like? If you take away all familiarity, the continuation loses its meaning; if every decision is the same as before, the new world is just another background image.
The building, terraforming, and power cycles that Gaia Project retains let familiar players recognize the kinship; the changes in research and spatial relationships require you to set aside certain habits you have already formed.
In other words, experience can help you begin, but it cannot replace observation.
This also gives "play it one more time" another layer of meaning. You are not just trying to perform last time's moves faster; you are watching how a familiar design language tells a different situation.
The co-author credit matters here as well. From the prototype to Terra Mystica, and then to the new work in space, the team's deliberation cannot be compressed into one person's moment of inspiration.
4. When factions and abilities no longer have only one pairing
By Age of Innovation, Helge has placed variation even closer to the starting point.
Feuerland's official page lists his author credit and explains that this is a standalone game in the world of Terra Mystica. Faction, terrain, and palace abilities are no longer locked into the same set of correspondences; books also become an important resource for development and actions.
Capstone's official introduction further shows that players advance their development through building, upgrading, and combinations of different abilities.
From this we can understand the new question it raises: when the starting conditions are recombined, how exactly should a faction grow?
Being familiar with a name no longer means you already know what your faction can do in this particular session. You still have to read the combination in front of you clearly and judge which opportunities it can connect together.
I quite like looking back at that early prototype from here. The original different factions and terrain, after many years, did not merely become an ever-longer list. The design also changed the way the parts connect to one another.
Of course, more combinations do not automatically equal a better experience. If choices lack relationships, they only become a memory burden; what is truly interesting is discovering that these conditions can support one another and also hold one another in check.
The official page also preserves a practical piece of follow-up work: after a large number of games, three factions showed strength differences not fully exposed in development testing, so an adjustment was released and included in later versions.
This reminds us that publication is not the day design judgment stops forever. Players bring the game back to their own tables and will try paths the developers may not have foreseen. Hearing these results and then deciding how to respond is also part of a work's continued life.
5. What he wants is a game you are willing to bring out again
In a 2025 interview with him, Helge described his daily life: he works part-time in art therapy at a psychosomatic medicine hospital, and spends the rest of his time on game development.
This is his professional experience; it cannot be used to infer that playing his board games has therapeutic effects, nor can every rule in the game be interpreted as a mapping of clinical work.
What connects more directly to creation is the preference he mentioned in the same interview: he pays attention to games worth playing repeatedly and is not satisfied with constantly trying new things while playing each one only once.
This sentence provides a very good observational thread for the works above.
From faction differences to tech combinations, from fixed connections to variable starting setups, what he seems to reopen again and again is not "how much more content can the box hold," but "how many different possibilities can the same box of things let people see." This is my understanding of the connections between the works.
His and Anselm's reworking of the older game Kaivai also lets us see how time returns to creation. When talking about Feya's Swamp in 2025, he explained that they did not simply do an unchanged reprint, but adjusted some rules, pursuing a shorter play time and fresh possibilities.
There is no need here to write every step as a negation of the past. When an author faces an old work again, he can keep what he wants to keep, and he can also acknowledge that today's self has new judgments.
I think this is perhaps the most moving part of Helge's experience: a long creative journey means more than watching the calendar pages turn. It means that after many years, you are still willing to sit down again with that old idea and see whether it can become clearer and more alive.
The next time you put away Terra Mystica or Gaia Project, you may still be thinking about the opportunity you just missed. Switch factions, switch maps, or just switch your understanding—and a new story seems already to be in front of you.
And a world that a creator spent a long time building may gain new time at the moment players are willing to open the box again.
