@draugnar, I don't fully understand your 2nd post. Are we saying something like....
1 - Nomination process, all players can submit gambits and the GamesMaster (GM) decides on the best three for each country.
2 - Allocation: Players 1-6 are allocated England and must self select and argue for their preferred gambit. They advise the GM of their selection in secret, and can argue for/against none or more in the forum. As the identity of players 1-6 are secret they can also involve themselves in the arguements of other countries. Players 7-12 are allocated France, etc, etc.
3 voting : a ballot paper is produced and players vote for their preferred moves. Every player has 7 votes (one for each country) A time limit is set, people who do not vote cannot receive votes.
4 Resolution: The gambit with the most votes is used. The GM draws lots in the event of a tie.
5 - Nomination process for the next moves.
6 Players 1,7,13, 19, 25 and 31 are allocated England, players 2,8, 14 etc are allocated France etc, and the process of self selection, debate and voting continues.
The idea is that the diplomatic and debating skills are judged more so than the stragagy of movement. Switching countries contantly takes away any bias in country selection.
