I hope it will be Iron Gods. Like someone once write:
"
The way I see it, there’s two basic kinds of characters you can make for Iron Gods: characters who accept technology and characters who don’t. Characters who accept technology are probably going to be interested in using technology or figuring out how it works. Whatever their reasons for doing so–greed, curiosity, convenience–they’re the kind of character who’s going to pick up a laser gun and either use it or sell it. Characters that don’t accept technology are going to do the opposite. They’re not going to use the tech they find and chances are, they’re going to try to break it.
"
This will give nice options to create PC not to mention how it can make tension between party members.
I think they can even use some of the current epic rules with bit of twisting, if we think of Nanite bloodline for sorcerer and how to use that NPC/PC: "The nanite bloodline has some cool powers. At low levels you can use the nanites inhabiting your body to coat your weapon and poison your enemies, or use the nanites to improve your skills. At later levels you can use the nanites to heal your own wounds, avoid critical hits, and even become a living swarm yourself. "
Thinking of first game and Harrim how about: “A cleric with the iron priest archetype. This character believes that the Rain of Stars which brought technology falling from the heavens was a divine event. The gods intended these objects as a gift for the people of our planet to use as they desire.”
There have been many players who have asked for Gunslinger, this would be great AP for it: "The techslinger archetype swaps out some of the gunslinger’s deeds with new deeds that involve using technological guns and gear instead. It’s quirky, it’s thematic, and it’s a chance to finally play a gunslinger!"
