About Eversim

Eversim specializes in creating simulation, strategy and role-playing network games. Its products are dedicated to public and to professionals of defense and security sectors for training and learning (serious gaming).

The development of these innovative products is backed by such prestigious bodies as Bpifrance, the Direction Générale de l’Armement (DGA) and CNC.


Eversim was founded in February 2004 by three partners: André and Louis-Marie Rocques and Pascal Einsweiler. The company is based in Lognes (Marne-La-Vallée) east of Paris and receives financial backing from a group of investors from Ile de France.

Eversim’s founders have worked together for over twenty five years in the world of video games, and were around when the industry was in its infancy in the 1980’s. Between 1987 and 2003, they created, under the Silmarils label, more than thirty products for consoles and computers  that were sold throughout the world.
