Imagine running your city’s bus system, building farms on land you know, or designing railways right where you live. A new wave of simulation games is letting players do just that by tapping into real-world map data from OpenStreetMap (OSM). These games offer a uniquely personal connection, turning familiar streets and landmarks into your virtual playground and management challenge. The big surprise? You can actually manage your actual neighborhood or famous landmarks around the globe!

What Are Real-World Map Games?
These aren’t your typical fictional game worlds. Titles like City Bus Manager, Global Farmer, NIMBY Rails, and Logistical: Earth use OpenStreetMap, a collaborative, open-source map of the world built by a community of volunteers. This rich dataset includes everything from streets and buildings to bus stops and even field boundaries.
Game developers tap into this real-world data to create incredibly detailed and familiar game environments. For example, in City Bus Manager, the streets, buildings, and bus stops you see are based on actual locations. The game even simulates passenger behavior tied to real-world points of interest – schools get busy in the morning, while clubs attract passengers on weekend evenings.
According to Niklas Polster, co-founder of PeDePe, the studio behind City Bus Manager, using OSM was initially a technical challenge, but the payoff was huge, giving them access to a whole world to build their game in.
Why Play in Your Own Town?
One of the biggest draws is the deeply personal connection. Players often start by loading up their own city or hometown. Thorsten Feldmann, CEO of Thera Bytes (Global Farmer), noticed this at Gamescom 2024, saying “every single booth visitor” wanted to see their own postal code and house in the game.

There’s a special thrill in being able to manage or transform a place you know intimately or one that’s instantly recognizable, like Buckingham Palace in Global Farmer‘s marketing. Feldmann notes that players creating their own stories around these real places can feel more impactful than in purely fictional settings. Taking control of a familiar space and shaping it, even virtually, adds a layer of emotional engagement.
For instance, the original author felt a strong pull to get the bus routes “right” in their simulated city, perhaps reflecting real-world concerns about public transportation quality. This desire to improve or optimize a familiar system is a common theme. Polster mentions their City Bus Manager community is full of public transport enthusiasts, some of whom were inspired to consider careers in the field after playing.
The Challenges of Real-World Data
While exciting, using real-world data for games isn’t without its hurdles. Games need to be fun and balanced, and the real world isn’t always designed that way. City Bus Manager, for example, provides extra financial support in smaller towns where realistic bus routes might not be profitable. This shows how game design sometimes has to smooth over real-world complexities. Some players have even reportedly contacted their local transport agencies with data from the game, mistaking the simulation for a perfect model of reality.
Another challenge is the data itself. OSM is built by volunteers, and while extensive, it can have errors or missing information. Polster says this can break specific areas in the game, requiring developers to manually fix issues.

For games like Global Farmer, density of data is key. While roads are well-mapped, detailed field boundaries are often missing, creating “grey areas” where farming gameplay can’t happen. Developers sometimes add tools, like map editors, allowing players to fill in the gaps using satellite images, but this requires extra effort from the player.
The good news is that because OSM is open-source, players can actually contribute to improving the data. If they find an error in their area while playing, they can fix it directly in OpenStreetMap, benefiting both the game and the real-world map for everyone.
Blurring the Lines Between Game and Reality
Management simulations have always aimed for a degree of realism, and integrating OSM data is a powerful way to achieve this. It allows players to interact with environments they know and care about, adding a layer of meaning that fictional maps might lack.
Navigating the imperfections of real-world data while still creating a fun game can be frustrating for developers, as Feldmann notes. However, finding solutions that connect back to the real world is also incredibly rewarding. This merging of familiar reality with simulated control offers a unique gaming experience that’s both challenging and deeply engaging.
