Since I havent gotten any feedback, then I thought I should make a separate thread about my idea.
3 different tribes commit to settling a united village, where everyone can build simultaneously their own troops, wall and special building.
The bonuses might seem at first too OP to even consider, but then again every player loses 1 cp slot and gains only 1/3 of the income of normal village so this should balance it out.
Reasons I think this is beneficial:
*It might help the multiaccounting situation by helping honest players cooperate more closely.
*It would help kings and dukes to contribute their tributes back to kingdoms in a way that governors can also benefit in development.
*It gives an extra step in long and boring midgame to make it more exciting.
*It incites more battling.
*It brings whole lot of new strategies to the table.
*Its never done in any of this type of browser games.
I elaborated more on this idea in the thread "merging troops"
