Ok, so i know that this would be too difficult to do on a real gameboard in your livingroom, but what if there was a way to play online RISK where players could go back in time to previous turns to bring in some reinforcements to themselves for previous turns and change the trajectory of the game? This would mean that the entire game would shift back to previous turns with automatic replacement of troops and cards and possible reinstatement of eliminated players. Players would have to structure themselves differently to prepare for a return to old turns.
I see a lot of weird ways to play RISK (nuclear, zombie, etc.) So i just thought I would ask for feedback to see what others thought about it...
