Okay, thanks, I see.
I think some post-nuclear gammes would fall into that category, I guess ?
Yes, some of those games could indeed, though it really depends. There is an even further and smaller sub-genre called "atompunk" that those games would fit into though, like Fallout. Early cold war era, that one is.
So any of the devs confirm if my dieselpunk guess is correct, incorrect, or if this is the first time they've heard of the word "dieselpunk" :P.
