I'm really glad that the game system quickly found a suitable background for you to apply! 

Yes, in my notes, I've even defined stats like electronic warfare defense and armor to create a near-future setting. It turned out to be easier than expected—if the opposite roll succeeds, the defense is successful; otherwise, the EW action take effect, and so on. You can use it on magic, mind, even TRPG skill checks.

Right now, I'm working on expanding the factions for a World War II setting. Before adding more unit stats, I hope to demonstrate how unit design can be done purely through the existing rules. In fact, I just uploaded an update! Feel free to give it a try whenever you have time!
