Ryan Green told TODAY that his game, called [That Dragon, Cancer](http://thatdragoncancer.com/about) and set in the family’s house and with hospital scenes, would help his family remember Joel and prompt a larger discussion about death and mourning. The game’s website states it allows players to”relive memories, share heartache, and discover the overwhelming hope that can be found in the face of death.” Poems and spiritual messages appear throughout the game, Green said, and it even includes Joel’s laugh. ### See The 15 Best Video Game Graphics of 2014  Call of Duty: Advanced Warfare.
