hello, about the trailers I think it should put a maximum resource quota arrived at a certain level of trailer created and continue to increase the number of rubies.The number of resources requested is too important at my level for me to launch new trailers, indeed 2 billion of each resource to create a castle at 0 point seems too high.The game and its interest would be increased if you could more easily build new castles and you would also win by increasing the number of rubies.thank you and have a good day
