I literally have been playing this game every day since I've heard of it about a month ago. I've enjoyed the game so much and have fun growing my city and now alliance! However I have 1 flaw with the game. As much money as I have spent as well as partners in our alliance. I'm not too fond of how the rise in costs of stations as you expand your city. I've spent about 200 bucks total in the game to earn credits since that seems to be the only way you can expand your manpower (which I think should be an easier way than having to buy the credits). I don't mind spending money on a game I enjoy, But there should be a way to hire new staff members than having to buy credits. Maybe I haven't figured out other ways, But being still new to the game, I haven't found any other way to get staff without needing credits. But The cost in stations as you grow should be a bit cheaper than what they are. Just my thoughts.
