OP, if you’re familiar with Malifaux (and if not it’s a wargame with weird west setting, and one of the factions is mine workers with steampunk robots) there is a ttrpg version of it called Through the Breach, which I’ve always thought looked cool.

Has a couple of unusual design choices (uses playing cards instead of dice, semi random charger [not like, 3d6x6 straight down but like, randomly chosen but equal in value arrays of stats, designed for each campaign to conclude in like players*4 or 5 sessions) but the setting is pretty neat.
