Many thanks for your feedback!
I forgot to mention that having a "goal" in form of a blueprint you want to turn into a flyable ship would be something to keep people motivated.
Weeks of gathering resources (which is nothing else than farming) to achieve that defined goal works out nicely.
But doing the same just to test some ideas? I´m not sure about that.
What if you get killed and your resources stolen before even coming that far?
What Falstaf mentioned:
<< Practically this means a person could create blueprints without any investment. <<
There could be implemented some kind of fixed cost for creation of a i) big, ii) medium or iii) small blueprint.
But still, you can do little with said blueprint, if you don´t turn it into a ship.
So it´s not like you actually get something for free.
Best regards,
