Hi guys,
My apologies if this has been covered before; I searched but only found one thread that came close to what I'm looking for and that didn't go far in-depth. This is also my first post to the Paizo forums and I'm still relatively new to Pathfinder, so forgive my ignorance, as much as I may have.
That out of the way, here's why I'm posting: I'd like to figure out a way to incorporate sci-fi elements into the world of Golarion. I know that there are many systems out there that do this already (Shadowrun, Alternity, Spelljammer all come to mind) but from what I've seen, those blend the two universes into one far more than I would like. I'm sort of the Michael Bay of our roleplaying group; when it's my turn to tell the stories, I go for the big and world-altering stuff. I don't want a blend of sci-fi and fantasy, I want a clash. I want to figure out a way for Golarion to be invaded by advanced races who possess technology, and I want to craft a story that has our archetypal fantasy heroes fighting through these forces.
A somewhat parallel experience might be Resistance: Fall of Man for PlayStation 3. In that game (for those who haven't played), WWII is somewhat... we'll say "interrupted" by the Chimera, an alien life form that spreads from Russia into all corners of the globe. The Chimera have incredibly advanced tech and weaponry, which forces humans to take more desperate measures and careful planning. They can't brute force their way through these guys.
I'd like to make something similar to that. From what I've seen, most blends of sci-fi and fantasy focus on the former and incorporate the latter. It's usually a future that ALSO has magic, not a medieval fantasy that ALSO has tech. I figure if I set campaigns during an invasion it gives justification as to why tech isn't everywhere and it will keep the overall "fantasy" vibe, but I need some help and ideas on mechanics. I've been tossing all sorts of things about in my head, including having guns fire more like spells than firearms, to further emphasize this is strange, alien technology people don't understand.
I know this is all very bare bones, but I'm wondering if someone else out there has done something similar, if anyone has ideas for how to structure the campaign, or what-have-you. The Advanced Race Guide and Ultimate Equipment have been amazing tools for this, as I've already created a couple races and tech armor.
So, would anyone like to throw their hat into the ring with me? Does anyone have some ideas of how this could work? Or maybe you've tried it and know it won't work? I'm looking for ideas, feedback, your homebrew classes, weapons, armor, items, etc. Anything to get this to go from "vague idea" to "playable material."
Thanks!
