i am sorry , but i dont know what name what chosen for World 3 .
I want to make a suggestion for World 3 if I'm allowed . this suggestion is stolen from other 2 games similar to our game. I think many players here tried those games .

for World 3 let's have a game deadline. I do not know exactly how but it might be possible to depend on the conquered GOLD castles.
these golden castles will be abandoned and the alliance that conquers most castles will be the winner of that round. the round must also end when the golden castles are no longer to be conquered . There are many warriors in the dam. it's not a good idea to turn fighters into farmers . ( sorry i was read that WALL bug )
