How people respond to change will ultimately determine the degree to which landscapes of coexistence between people and megafauna can be realised. Over 2.7 billion people play online games on a regular basis, but very little of this game play time is used to advance our knowledge or to tackle environmental challenges. In this talk, we will 1) present the games we have used and the data we have gathered with over 700 game players in Europe and Africa to understand people's decisions towards conservation of land and wildlife; 2) provide a roadmap for the use of online games as an experimental and observational tool to collect data on people's decisions in complex social-ecological systems; and 3) discuss the potentials, limitations and ethical concerns when collecting large scale data on people's decisions.
