GameUp is one of the largest educational game platforms available, with games by 43 partner organizations and BrainPOP itself. In the process of curating games for BrainPOP’s 800+ educational topics, we have explored different approaches to making our internally-developed games over the past 7 years. BrainPOP went from developing 3 content-oriented games to developing 3 skill-oriented games. We’ll talk about why we transitioned, what worked, and what didn’t work throughout the process.
