another thing could be to create a King/Queen element in the game.... i tried a game where one of the missions in the game were the diplomatic/democratic part... it was cool.... it meant that its was not all about being a grand/big player....
In tentlan it could be like... that every 14 day or once a month a voting throughout all the land... to either keep the current ruler or change the ruler with a new better setup for the land of tentlan....
Every tribe has one vote... so the tribe members has to agree on that... and most important... they cant vote for their own candidate.... so the game brings more diplomatic strategy into it....
The candidate from a tribe has to put up his/her´s setup for their ruling at least one week before election so all have a chance to choice the right one....
The setup could have the power to decide ( % of attack limit between big and small players.../ numbers of attacks pr day on same player..../ use of free transfer of troops.../ and so on and so..... there is many types of changes that could be made... the more there is the more fun and tricky... it will be funny to see the outcome of the vote....
When a King/queen has been elected.... their ruling setup will start... and cant be changed until next election..... and perhabs the tribes enjoy the way the rules are... or is mispleased... so a new type of ruling and King/queen needs to be in place.....
Just some ideas.... :))))
If players gets more influence in the gameplay.... they are also more villing to not just quit.... but actually try fighting back and also use some money.... so our dear devs can use more time on evolving this great game.....
