I wish it DID work in GBG. Negotiations are a lot more fun with the extra turn, and now there is a castle you need 15 negotiations a day for speediest advancement. I feel a little bullied because you can get past these with diamonds, and it feels like Devs are twisting our arms to get us to use more diamonds and hopefully buy more.
I do appreciate every player who DOES pay rl cash for diamonds because that is what keeps the game going for all of us.
