From the campaign:
America, shortly after the first transcontinental junction in 1869.
Railroads are developing all over the vast expanses of the wild west, and business is booming. It is a time of adventure, progress, and opportunity. The transcontinental junction was a great milestone in American history, a first step that reshaped a whole continent.
In SteamRollers you are a railroad entrepreneur building a network of tracks and a fleet of train engines to secure freight delivery contracts before your opponents.
The campaign has already passed its funding goal. So it's on to stretch goals for the next 28 days.
