In the 1900s version of the game I mentioned above, one of the villains was a PAG* whose armor was powered by steam & hydraulics. Instead of repulsar rays like Iron Man, he had twin flamethrowers.My second Preference would be Age of Exploration to Steam Age, just to see Clockwork Ironman and a Swashbuckling Pirate Vigilante
* Power Armor Goon; HERO slang
