I personally would like to see open votes an option for both game generated referendums and those initiated by players. For example, I could see a republic choosing a representative system of voting but wanting the vote to be open so as to hold the senators accountable. Or not. More choice is a good thing in my mind. I am curious to know how many historical democracies or republics kept the votes of it's representatives private... I am betting that there were few of them.
