1 Have you seen Arcane? It reminds me of the game Eberron.

I have not seen it, but I am familiar with League of Legends. Just in terms of progression of influence for the genre, it basically goes:

WWI/Edda/Kalevala => LotR/Hobbit => Warcraft => DotA => LoL

In terms of steampunk as a genre, the hardcore/fringe steampunkers will insist that Odin's spear is a firearm, thus increasing the range into the past for the genre. Though I do not believe one bit that Nordic people before Christianization believed in steampunk or that Gungnir could shoot "missiles" or "projectiles", the living tradition can believe whatever.

And to go deeper, one other example, at the Tolkien-level, some folks believe that Gandalf shoots a pistol right before he disappears after the goblins attack in the mountains. Though I do not believe Tolkien actually wrote it to mean a black powder pistol (probably meant it to be a grenado or some other pre-grenade), I have no problem spreading this idea.

…and when goblins came to grab him [Bilbo], there was a terrific flash like lightning in the cave, a smell like gunpowder, and several of them fell dead.

The Hobbit, Chapter IV Over Hill and Under Hill

But what I can say for certain about steampunk, Warcraft definitely latched onto it by Warcraft 3 at the latest, just in terms of gunpowder weapons.

And in terms of automotans/androids, some fringers say the norse dwarfs (not the Tolkien dwarfs) are androids. If anyone has ever noticed the Aesir poster I have on my wall, that came from an indie comic about just that: Dwarf Androids.

I've thought about it a lot, though I'm not as certain about the lineage in terms of Eberron. It's definitely at least a fork from

LotR => D&D et al => Eberron

But the similarities between Final Fantasy (I only played up to XI) and Warcraft III are undeniable. I'd be surprised if neither of those influenced Eberron, but less so if only one of them did. But because of how pop culture progressed, even if only considering North American Western Pop, I'll assume both.

And those are just direct lines. DotA, for example, was a bit more complicated than that. It took from everything, including sci-fi.
