Soviet Republic. An actually difficult and very complex game that is mostly about becoming independent from imports.

To do this you have to build factory complexes to produce your own building materials, and ship them with trains closer to your cities where your construction offices, stacked with vehicles you have to buy by hand, will then carry out construction. And by carry out I mean a truck will first physically transport construction equipment like bulldozers, excavators, cranes, etc to the construction site.
