– That Dragon, Cancer developer Ryan Green Earlier this year, five year old Joel Green passed away after a four-year battle with cancer. The experience of caring for the child forms the backbone of the upcoming game That Dragon, Cancer, which his father, Ryan Green, is making. Today in a new interview with Joystiq that appears alongside a Kickstarter for the game, Green discusses how his attitude toward the project has changed since his son died. “When we evaluated which scenes would make the cut in the game, we asked ourselves, ‘Does this scene help the player love Joel more?’ And if it didn’t directly contribute to that, we cut it or we rewrote it to make sure that Joel became an integral part of the scene,” Green says.
