looking up dieselpunk showed it had the aesthetics of diesel technology from the interwar period (the time between WW1 and WW2) all the way up to the 1950s but when it comes to steampunk it's more centered around the 19th century such as the Victorian era of Britain and the Wild West of the US. But it would seem more aesthetically fitting for a combination of both steampunk and dieselpunk to make sense because WW1 is in the time "gap" between those two styles

So what you're saying, is that this is some sort of transitional period between the two styles? Makes sense, I suppose. Considering how rapidly things changed during that time.
Going from marching across open fields, rank and file, wearing brightly coloured uniforms, and horses, to using things like machine guns, tanks, and aircraft.
Maybe this could be it's own thing? No idea what to call it. Trenchpunk? Eh, doesn't have the best ring to it.

yeah that's what I am thinking since it seems to make more sense with the lack of any distinct aesthetics associated with ww1 beyond what we would see in either steampunk (such as the extravagant uniforms we saw the Imperial German, Russian and British officers wearing during that time) and dieselpunk (the Mark 1 tank made by the British during ww1 although the engine itself used petrol or gasoline as opposed to the oily diesel fuel and the German A7V and use of machine guns based off Hiram Maxim's revolutionary design)

Personally Trenchpunk or Gaspunk might be the best fitting names in my opinion since ww1 usually brings up trenches and the use of terrifying chemical weapons. Others might think differently though so who knows.

Hmm, I guess so. Good points there, I must admit. Though I think Trenchpunk might be the better name, considering the.. implications of the latter.

oh yes... forgot about those...

"They rode into the war on horses, they rode out of it in tanks."
-A fitting example of how quickly tech changed in those 4 years.

I guess people don't; use WW1 as much because its seen as 'boring' compared to WW2, and how the technology of the time isn't as 'cool' looking as WW2's stuff was. (Even tho WW1 gave us the first tanks, and well, grenade-crossbows before proper anti-tank guns were mass produced)

Trenchpunk does sound kinda cool.

I think a few games have done WW1 in some degree over the years! The most recent ones of course being Battlefield One and Verdun, but older (and more fantastical) entries include Necrovision (WW1 meets Doom-ish Hell n zombies stuff) and 1917 Der Unberkante Krieg (short horror game involving, well, robotic looking dinosaurs attacking a trench, based loosely on accounts of 'monsters' attacking trenches', possibly gas induced madness)

That's one thing that very much interests me, is the rapid advancement of the technology that takes place during that span of time. And that leads into the strange/somewhat wacky weapons and such that came into being because of that break-neck evolution.
And I think that this 'trenchpunk' thing could have it's own place because of it. Not just because of the strange tech, but also because of the possibility of adventure than many of the punk settings have. Likely a fairly dark one, for obvious reasons, but it's still there.
Aside from BF1, the only other game I can think of in that setting is Valiant Hearts. Good game, kinda sad though. Worth watching a play though of it, if nothing else.

Have you played the Bioshock franchise? I would recommend Bioshock Infinite, as it's set in 1912, 2 years before WWI, and has a lot of trippy steampunkish technology and themes relevant to that time era. I would also recommend the other games as it's just a really damn interesting franchise, but Infinite fits the most to what your looking for.

I played the first one, and watched play-throughs of the other two. Interesting themes.
