Not sure if this is the right place to post this, but I figured that Pathfinder Adventure Path - General Discussion would be a good and appropriate place to post this.
Okay, so I was going to run a Kingmaker campaign but, since I already am running a Northlands campaign and the way that I envisioned Kingmaker was very much a Game of Thrones-esque adventure path with some very clear Celtic and Norse tropes spread throughout the campaign, I did not want to create overlapping campaign themes. As such, I found myself at a proverbial impasse regarding what to create, since I still want to eventually create another campaign on these messageboards.
That said, I have a few ideas that I think are pretty cool and wanted to post them here so that community members could get a chance to comment on them, tell me that I failed a sanity check for coming up with them, offer me glowing praise for cool concepts, and such.
Without further ado, here is a not-so-complete list of alternate adventure paths and some details on them.
1. Space Skull and Shackles- Alternately the most and least complex of the reskinned campaigns, this would cast the characters as recent fodder aboard the Wormwood, a notorious starship piloted by space pirates in Golarion's universe.
The campaign would start in the last half of the first book, for those who know what that implies.
The players could use any official Paizo race and could, upon request, be allowed to make a new player race that is basically a foreign alien race (With the option to work with the GM on statting up new racial abilities nor present in the ARG such as bioluminescence or extremophile).
The campaign would follow a pretty similar path but, instead of sailing the seas of The Shackles, the players sail the vastness of space and can land on the various planets and moons.
Major NPCs would, quite obviously, be replaced by flavorful alien counterparts.
The Hurricane King would be reskinned as the Regent of Yawning Void, the brutal leader of all the space pirates, an alien who brutally hunts down those who do not pay him fealty. His base is at the edge of the largest black hole in the known universe. The final fight with him for dominion of the Space Pirate Empire would include him (Unique Gravity Elemental with a touch like a disintegrate spell, nearly impenetrable, artifact-level armor that contains the collapsed star that is his body, and similar awesomeness!), his loyal Kasaath bodyguard that is a gestalted Sorceror (Starsoul)/Soul Knife built around Dimensional Assault and blasty stuff, and an Android assassin by the name of Nyx who has a fatal obsession with one of the characters and whom uses her skills as a gestalt Slayer/Investigator to try and eliminate that character.
Technology would also be rampant in this setting, fitting the sci-fi theme.
2. Way of the Wicked as a Space Campaign- There are the two cardinal sins of tabletop roleplaying right there: evil PCs and space! Still, one cannot ignore the awesome notion of PCs escaping from an interstellar prison in order to bring low the federation of peace-loving worlds that imprisoned them,
Changes would be similar to the previously mentioned alternate APs, but would also feature a massive twist in the plot.
3. Kingmaker in Space- As mentioned by many people, X with space makes things better and this is true with Kingmaker! Especially since I have PDFs with kingdom-building rules for structures similar to Android Factories, Orbital Cannons, Pharmaceutical Structures, Psionic Resonance Chambers, and stuff.
4. Inverted Wrath of the Righteous- Instead of the classic 'heroes slaughter demons' campaign, consider this: what if the celestials, angered at the wickedness of Cheliax, opened an angelic rift in the heart of of Cheliax's mainland and have begun to occupy the surrounding countryside, turning the area into a bastion of good. The PCs, favored agents of Thrune, are tasked with ending this occupation along with the rebellions that will come during the crisis.
5. Wrath of the Rightous for Angels- As Wrath of the Righteous, but the PCs are angels/archons from the Heavens. I am unsure of character creation rules for the races, but the campaign would be much more high octane than most Wrath of the Righteous campaigns.
6. Carrion Crown in Ravenloft- Considering that there are pretty good replacement areas and NPCs that fit almost perfectly and seamlessly into the Carrion Crown adventure path, I think this is a pretty good concept.
7. Skull and Shackles in a Dune-like World- Pretty much as described. Sand-ships skim across the treacherous sands and pirates are a constant
