This is the non-desert version of the peace levels. Same concept as the first batch of scenarios, with their military elements removed and replaced with a different set of challenges. Some were edited more than others, with the third map getting a huge chunk of the edits.
Via Cassia is based on the Italia map by Marcus Dominus which is in the downloads section. The Lost Colony is from a map called Roanoke, which is part of the "New World" campaign by Dragon2. It's an alternate map though and was designed by Incontinentia (as indicated in a scenario design forum thread on Roanoke). Terra Nova is based on a map called New World by etts which is in the downloads.
Level I
Via Cassia
"The Price of Peace"
Twin tasks of dealing with an export emergency as you wind your streets thru the existing native settlements.
Moving goods across the 3 strips of land will be a main concern. Plus, you'll need to import more than a few items to address your city's lack of raw materials. A few abandoned mines may offer some help. Loaded as a saved game.
