If you are a board game enthusiast, I think you will really enjoy British Rails.  Using the system originated by Mayfair Games Empire Builder, this game consists of a map of England, Wales and Scotland.  You pick up and deliver cargos to various cities to earn money.  You use this money (you are given some money to start the game) to build rail lines from city to city by drawing lines with crayons/markers.  There is a deck of over 100 cards, most of which have three cargos on them.  Since the cards are drawn randomly, the possibilities are virtually infinite, so each game is different.  By the way, this is shown as a toy, but it's not - it's a board game.
