An NFL themed version that according to the box 'includes all 31 NFL teams' - 30 by my count on the board and in the league at the time - with low-ranked Colts and Cardinals as properties at the cheap end of the board and 1997 Superbowl winner Broncos at the other. Each Railroad is a pair of teams.All the cards and other components have a football theme. Strangely the rules aren't 'translated', but have a preamble that explains the differences, e.g. stadiums equate to hotels. - BoardGameGeek
