I spent an awful lot of time on a basic set of master data. In fact the design of a single “product tree” for the basic types of trucks and ships took me one and a half day. The result are around 50 products and about 20 building types. These do not include any consumer goods. It’s just the raw and intermediate materials required to produce the mentioned vehicles.

As such it will

1. be impossible for a single player to produce any such product on himself and
2. require a very structured approach of the early players to build up the initial industries.

I will probably let the system sell some vehicles when the game starts because otherwise we’d run in a serious chicken-or-the-egg kind of problem ;-)
