ImmoStory City
ImmoStory City is a real-estate game set in a real Belgian city: buy, renovate and rent out in Ghent, Antwerp, Brussels and seven other cities. Real registration duties, the EPC E and F renovation requirement, a bank that watches your budget and listings from live Immoscoop data β with every map built from OpenStreetMap. Now in beta for iOS and Android, in NL, FR, EN and TR.

Case study
Project overview
Challenge
Property games play in fictional cities with fictional rules β there was no fun way to learn how Belgian real estate actually works.
Solution
Every city is built from OpenStreetMap and every rule has a source: Statbel, Immoscoop, VEKA, ECB/NBB. No loot boxes, educational by design.
