Workers & Resources: Early Start DLC

Workers & Resources: Soviet Republic is a cross between an automation game and a city builder, with relatively complex logistics for a city builder. I am particularly fond of the organic, demand-based logistical challenges of distributing resources to meet the needs of your citizens, and managing realistic mode construction.

The upcoming DLC adds more buildings, vehicles, and a tech overhaul to allow starting the game in the 1930s.

Edit: caveat for those interested in the game: it uses undisclosed AI "art".
