There's now a free prologue-style preview for the minimalist resource management sim Masterplan Tycoon, just released this week in the form of Masterplan Tycoon: Foundations. The demo takes you through early stages of building out your empire of flowing stuff, letting you plop down camps, quarries, farms, and factories.
Masterplan Tycoon's basic concept is that it's more a blueprint or outline of a resource management game than a dedicated, in-depth resource transportation and logistics extravaganza.
