When you hover over the word BUY when you are going to buy a building it should tell you how many max workers it is going to add. Just an idea because I am not very far into the game yet and if I buy too many I get screwed. I know I could just distribute less workers to food and more to other things to even it out but still it would be a nice feature to see exactly how many it adds :P
I think some negatives things should come up every so often like FBI investigations and you have a wheel and you either get penalized or you get away scot free. Just in my opinion to make the game less boring at higher levels
