What I want is to have the company carry a certain amount of passenger, freight and mail traffic. They must also own a certain amount of buildings that are valued at a price I will determine at a later time and must have an okay profit and obtain a certain amount of company and player cash by 1960. If they get to those points before or during that year, they'll get a congrats and end game notice. If they don't, I want to give a notice of failure. What would be the formula for that? Also how do I write up a briefing?
