Worst bridge simulator ever. I am a civil engineer for the US government and this game in no way simulates bridge building the way we do it. First of all you need to limit the materilas much more. And then you need to limit everything else. You need to be able to upgrade bridges in a way that saves the government money. You cannot spend money to build bridges. This is just not the way its done in this day and age. Human sacrifices are an acceptable loss that is calculated by a formula and this game does not know it. I cannot share this formula with you or the government will end me, but be sure it exists. Anyway, dont ever expect to get anywhere in life by being good at this game. Save yourself the time and skip it!!!!!!!!!!! Exclamation 1111!
