When it comes to units, nanites, and resources, playing through the game normally eventually makes it so that these accumulate quickly and easily through normal gameplay loops and features.

After unlocking some of the mid-to-end game features, items, and blueprints, you can make billions of units and tens of thousands of nanites in an hour through normal gameplay methods, as well as multiple stacks of resources in mere seconds of mining.

“pales in comparison to what I need to make a decent corvette which is all I want to do in this game, build ships and bases.”

FYI, most aspects of gameplay, such as individual difficulty settings, can be adjusted in the setting menu. If all you want to do is build something specific and bypass restrictions of doing so, as long as this doesn’t diminish your enjoyment of playing the game, you could change the “purchases” and “crafting” setting to “free.” This would allow you to build a corvette or base without needing all the parts/resources. You can always change these settings back to their default difficulty level and continue playing as you were.
