At the next launch of Microsoft Flight Simulator, the last update in version 184.108.40.206 asks you to download 21.5 GB. You will be entitled to various fixes -including the behavior and fuel consumption of the Diamond DA40NG-, and additional content such as airliners liveries, such as S7 for the Airbus A320Neo and KLM for the Boeing 787-10. For the full list of its content, see the announcement here.
Then you have the option of getting the latest World Update #4, which covers France and the Benelux countries (Belgium, Netherlands and Luxembourg). And on the French side, we are rather spoiled with several monuments and important buildings of Paris and La Défense business center, but also with castles, abbeys, lighthouses, bridges or even the cliffs of Etretat for example.
