I have a friend with cerebral palsy and we've been playing Imperial Assault for a few months now. The Star Wars Dice app has been **** useful in that time, as he doesn't have the coordination to pick up the dice and roll them himself. Previously, I'd either roll for him or hand him each die and let him drop them individually. Since I also take care of moving the figures around the map, handling the chits and laying the cards out for him to see, the app has granted him some sense of control over the game and a bit more involvement.
I love Elder Sign and would like to play that with him too and am prepared to handle all of the tasks requiring manual dexterity there as well, however, if there were a dice app for the game, it'd be just as helpful as the Star Wars one. Hey, could even incorporate it into Elder Sign Omens and then I'll buy a 4th copy of it! (Have it on PC, iOs, and Android.)
