Marianne

I am a French-based game designer and creative director, currently leading Moon Valley as founder and creative director. My work focuses on mission-driven video games that raise awareness around social and environmental issues, with an emphasis on inclusivity and meaningful player experiences. I have built and led teams to develop strategic and narrative games that blend ecology, health, and diversity, including Roots of Tomorrow and other titles such as Purple Town, Challenger Deep, Tricky Life, and Summer Time.

What drives me is a passion for storytelling, design, and impact. I share and infuse my daily work with these convictions to create games that can change perspectives and behaviors for the better. I also collaborate on research projects about the behavioral impact of video games and engage with the broader game and cultural communities to push for more inclusive, innovative experiences.
