Update with some new ideas..
There will be seasons and a season will end when there's only one nation left. Then the map and nations are reset and the players can choose their alliance and start over again. I would expect each season to be at least like 3 months but if not then we can change that because I doubt players will want to lose all their stuff every month or two. There can be elections for each nation for a new leader (or keep the same) either every month or every new season, we'll see. Perhaps an option for mutiny???
That's all so far.
Make sure to vote on the polls!
