Random, idle thought: a D&D campaign that includes an adventure (not necessarily a single session adventure, just a complete adventure) in each edition of D&D, in order.
How would you do it? Would you use published modules? One big module/AP? How would you handle characters between editions? Which versions of which editions would you use (ie Skills and Powers versus "straight" 2E)? What adjacent games would you include? Are there any editions you would NOT include?
