Babel, the Hove-based new media company, has passed Go with a web site for Infogrames Europe's title Monopoly Tycoon.
The company translated the site into four languages and a separate team tested them.
It has been localised for the English, French, German and Spanish markets.
Business development director Ben Wibberley said: "Places such as Pall Mall and Mayfair are obvious London locations and would look hopelessly out of place in a German or Spanish game."
The project is the first time one of Babel's clients has outsourced a whole package of services and comes as the industry begins to adopt the model of outsourcing non-core services to specialist companies The Monopoly Tycoon web site features branded wallpaper, a screensaver game and a Euro currency tool convertor for visitors to download.
Visitors can use the site's radio to listen to tunes from the Thirties to the present day.
