Idea is intriguing.
Is the game to be played chess, or a chess-variant?
If it's chess, I probably won't participate, because I don't have time to play fast games, and slow games can be affected by people using engines.
But if you play a variant (at least one non-standard chess piece for each side) then I might like to play (casting votes in a game).
For the past month I've been working on Move by Numbers, an experiment in what I've been calling "massively cooperative chess". The basic idea is that rather than competing against individuals, each game proceeds (and points are awarded) based on votes from people all around the world.
This project is very much in its infancy and still under development. If you find the idea intriguing or have suggestions for improvements, I'd love to hear what you think.
