The 14th International Workshop on Network and Systems Support for Games (NetGames 2015) will be held at the University of Zagreb, Zagreb, Croatia on December 3-4, 2015. NetGames brings together researchers and practitioners from academia and industry across the globe to present their latest research on the challenges of today's networked games, and to further understand the requirements and explore the possibilities of future generations of networked games. NetGames will also have a keynote and panel discussions with participants (or invited talks) from both academia and industry.
