Pen and paper works pretty well. Everyone who can read/write/count understand how it works and can be appointed as a political/citizen observer.
Moreover, if the count is public (not in the US but it’s the case where I vote) everyone can see the counting and get the number, all it takes is people having 2h to give to their country to help counting or just watch it.
This make fraud almost impossible
I woald advise other RPG than D&D, too many beginner look for D&D and nothing else, while tons of GM struggle to find player for non D&D games, as usual look for a club/meetup/shop near you
