My Queen, I think with the term "rat rod" it's more about how they're trimmed down and not very comfortable. Most don't have roofs or covers for their engines. It's my understanding they started off as just a plain vehicle designed for speed.
Do you write? I write sci-fi/fantasy.
LadyV, which game did you find challenging?
I've never understood the word "speculative", so you are one up on me.
Lady Silva! You snuck in on me. How have you been?
Well, I may be completely and totally wrong, but I understand it as an umbrella term for stories set in imaginary or future worlds, rather than the contemporary or historical one.
I missed your request for a better definition for that term because Lady Silva explained it the way I understood it.
