As the title says. Ive seen plenty of builds from both categories. If you search up either in the sites search bar (bottom thing in the airplanes dropdown), you will find a couple of pages worth of builds. Also a lot of my own builds would count as dieselpunk builds.
In other words, I think there's enough steam/dieselpunk stuff here to warrant their own respective tags.
@FishMiner excellent. Tag me on one steampunk and one dieselpunk build, preferably your own, so I can make tags.
@EternalDarkness As instructed, I have reminded you of this post 6 hours later.
Remind me in some six hours. I'm at work.
