The game is suck! As you level up, it gets worst and worst. France, level 100, you can not use all the trains you previously have. You have to atleast use some of the "keys" to unlock new but old trains. And each train only loads up maximum of 5. And as you send them to each task, it take an hour to complete. Unless you are lucky enough to get the 20 loads. I know you guys need to make money out of it, I absolutely understand that but dude, what's up with the trains as you level up?
