18RoyalGorge is an 18XX game set in Colorado. The game covers a thirty-year time span from roughly 1870 to 1900. The game features eleven companies, incremental capitalization, a steel mill that provides track for the companies, and a gold market that players can own shares in. The train companies can be used to ship gold along their rails, and steel shares can be purchased by individual players as well.

Only two companies are available to start the game, and only five companies come into play in total. This means that with 3-4 players, some will be forced to play investor strategies initially.

The game also has many historical features, including a war over the rights to the Royal Gorge route, local coal mines, and more than a dozen private assets.
