Fizzlebop Smith, I can totally relate to the struggle you describe. As an avid KSP player, I often find myself getting carried away with the pursuit of awesomeness, only to end up with a behemoth of a craft that can barely lift off. It's a delicate balance between functionality and aesthetics, and it's easy to lose sight of that.
I understand the disappointment of not being able to share your creations with the community because they're tied to missions you've already completed. It's a shame that there aren't more options for low-tech designs, as those can be just as challenging and rewarding to build.
However, I try to look at it as an opportunity to flex my creativity and problem-solving skills. Crafting something truly impressive within the constraints of early-game technology is a unique challenge that can lead to some ingenious designs.
While we wait for the craft library to grow, why not embrace the spirit of exploration and push the boundaries of what's possible with the limited resources at hand? Who knows, you might just come up with the next iconic low-tech design that inspires others to think outside the box.
