There’s been a shakeup at Asmodee North America, AKA the company that brings you Settlers of Catan and other strategy games.

Christian T. Petersen will step down from his role as CEO of the company at the end of the year. Petersen founded Fantasy Flight Games (FFG) in 1995 and served as its CEO until FFG’s merger with Asmodee in 2014, at which time he moved into his current role.

As Petersen exits his role, Asmodee North America will transition into two distinct business units: Asmodee North America Publishing led by Steve Horvath, and Asmodee North America Distribution led by Andre Kieren.

During his tenure, Petersen was involved with hundreds of game titles and was the lead designer on games such as Twilight Imperium and A Game of Thrones: The Board Game.
