{:prepare, proc, inst, ballot} -> ...
{:nack, inst, ballot} -> ...
{:prepared, inst, ballot, accepted_ballot, accepted_value} -> ...
{:accept, inst, ballot, value} -> ...
{:accepted, inst, ballot} -> ...
{:decide, inst, value} -> ...

- If a game state exists, then it was created by a user
- The game state can not divert.
