I'm not the biggest sci-fi fan, but I could clearly see the inspiration and love of Asimov in this Spark, and it felt very him! I'm also grateful for the way you put in the little parenthetical comments giving the DM/GM permission to do or change things differently, or explaining why certain aspects are important to include. That's something I feel many more scenarios and modules as well as Sparks need, as it doesn't matter how experienced I am, I'm always terrified to alter the work of someone else when I'm running it for fear of somehow ruining it by not doing it perfectly as laid out!
