This document discusses using popular video games to promote health initiatives. It notes that while some health games have been created, they suffer from a lack of visibility and advertising. The document proposes addressing this by partnering with the creators of hugely popular existing games like World of Warcraft and League of Legends to develop mods or additions focused on health topics. Specific examples outlined include a diabetes mod for WoW that tracks blood sugar and a stress management tool integrated into the competitive multiplayer online battle arena game League of Legends. The goal is to leverage existing gaming platforms and audiences of tens or hundreds of millions to more effectively promote health messages and programs.
