This is the first game that I've ever felt a need to review. The AI is incredibly bad. Your trains will park themselves and wait even if nothing is in their way and nothing will be in their way for the conceivable future. The game insists on making you lay parallel track as a separate track and then go through the process of creating your own stoplight system, only to watch your trains come to a full stop because of the bad AI. Computer trains do NOT have to lay parallel track and their trains pass right through one another. I'll give the game designers a hint: there should probably be a simple highlight setting to make a single track into a double track, and the game itself should handle nonsense like stoplights. A tycoon game that makes you worry about stoplights is missing the point of being a tycoon game. Just terrible design, and worse implementation.
