The Add-on Grand Paris Moulon - With the Express 91.06 through France from developer Creations AgoraS-114 plays in the area south of Paris. Also in our neighbouring country there is a big fanbase for the bus simulator OMSI. And there's no doubt that this is a wonderful country for bus travel too.
To the north of the Essonne department and to the south of the Yvelines department respectively, there is the French Silicon Valley. There are many companies and start-ups in the digital sector that are involved in the world of today and tomorrow. This is why the landscape in the OMSI map changes abruptly from modern business buildings to French small-town idyll or typical village character. This area is modelled on the OMSI extension Grand Paris-Moulon.
