I love old board games. Video games are cool, but they just don't have the same feel. Unfortunately, many of these great old games are no longer in print and are virtually impossible to obtain. Each box above costs $300-500 on the internet, with no assurance of its condition or contents. That makes the total cost of this game and its expansion pack somewhere in the $800 range, if you can even find it (Avalon Hill is no longer in business). Therefore I find the best way to play all these without your friends getting mad that you accidentally spilled coke on their valuable game is to make an inexpensive copy.
There are two ways to go about this. I will discuss both.
Step 1: The Fun Way
The fun way to do this is to draw it out. Get some particleboard, easily found at most hardware stores, in whatever thickness you want. Measure out and draw the sections on the game board on a piece. My board was easier, because I was first able to draw out the borders between territories and then use those as guides for the landscape art.
Next color in all the areas you need.This may take some experimentation with colors. I had to find three different shades of green as well as all of the other colors.
Take a look at the last two pictures. Success?
