When I was a kid, my brothers and I would make spaceships out of LEGO and then have pretend battles. I was always coming up with new, powerful weapons, like a laser that used only visible wavelengths so it could go through any forcefield people could see through, or a souped-up Starfleet transporter that just transported parts of the other ship’s engine or hull away, causing massive damage. It was great. I could give my spaceship any weapon just by imagining it and saying that I had used it.
Sadly, I learned that my brothers could neutralize any weapon I imagined, simply by saying, “It didn’t work!”
