Just the GDP. Everything else works. Maybe inflation? I don't know if any values could be clear cut.
I hope that CH continue to support the game by making trainers for newer versions. How ever i would be more than happy if CH took there time at making a trainer. While we were lucky that Caliber was able to make this trainer in a day a lot of trainers can take months to make. I believe a effective trainer could be made if people were prepared to wait for it and not expected it in a day.
I agree, but I didn't think anyone was expecting the trainer to appear overnight or anything. I'm sure all of us could last a while without one imho. I think people wanted to know weather one was planned or not. I think everyone here didn't want Cal to spend his holiday making the trainer. And we are thankful for what you have done for us.
Regarding the screen shots, I didn't know that increasing number of electricity stations gave an increase of money. Will try it in game.
