I think its a joke that the new boost buildings are for gold users only, i dont spend gold playing the game just like 70% of the rest of the people who play this game. Gree you should at least make the buildings available at a cash price even if its stupidly high. Or delete all the buildings and give everyone their gold back and bring them out as a cash building instead of gold. You have alienated most of your customers as usual with this crap
