If you want to see a movie version of this game...
Go watch The Lone Ranger currently in theaters. With a few minor tweaks to the script, it could follow the game exactly. It's already got a diabolical Civil War general turned railroad tycoon, an evil henchmen, a treasure in a mine and a the good guy seeking revenge for the murder of a family member. Even the Alhambra token in the game and its use in advancing the plot has a counterpart in the movie.
If you watch the movie with this in mind, it's not that bad...
