Dungeons and Dragons (D&D) is crowd-sourcing rules and features for a new edition. The last edition, released in 2008, was controversial so this is an attempt by makers Wizards of the Coast to get it right with fans, while recruiting new players.  You can even sign up to playtest the lastest iterations of the game as they are developed this spring. Perhaps as a parallel mission, CUNY Games should solicit ideas for how to teach with D&D?
