First, I have always wanted to run a game using Ken Hite's "Seas of Dread, Sails of Daring" setting that he outlined in the old GURPS 3E supplement, GURPS Horror, Third Edition, then revised (as just "Seas of Dread") for GURPS 4E in GURPS Horror, Fourth Edition. It might even supersede wanting to run Flashing Blades as a pirate game right now. Also, I'd kind of like to run ACKS in the Dwimmermount setting or Stonehell Dungeon in my Middle Sea setting using Delving Deeper, Swords & Wizardry Core, the D&D Rules Cyclopedia, or AD&D 1E with some of my own customized character classes. In addition, I wouldn't mind running a sandbox of Hârnmaster starting in Kanday in Hârn. Aside from these four examples of other people's campaigns/settings, though, I have some others.
- AD&D 1E: Flanaess Sector - I still have considerable work that I'd need to do, but in addition to the idea of using White Star, as mentioned previously, I wouldn't mind converting AD&D for the purpose.
- XXXXX: Metahumans Insurgent - This could be run using almost any superhero game. My preferences would be, in order, GURPS 4E, CORPS, Guardians, or Villains & Vigilantes. The idea is that the world woke up one day a month or two ago and a portion of the population had metahuman powers. The players would be in the upper tier, the portion that counts one in a million as members (500 points in GURPS, 200AP/200SP in CORPS, and standard starting characters in the other games). There would be a lower tier, one in a hundred thousand, that have lesser abilities, and the rest of the population have no metahuman abilities. The campaign would start with the world coming to realize that metahumans exist, and then trace the resulting collapse of society into chiefdoms ruled by metahumans and groups of metahumans. Or maybe some other outcome, depending on how things went. It would be inspired by the TV series Heroes, the movies Push, Chronicle, Jumper, Limitless, Lucy, and the like, and the comic book series ESPers. That is, no costumes, no silly names.
- RuneQuest 3 or 6: Time of the Gods - This is a relatively undeveloped setting in my head, of a world in the late bronze or early iron age where city-states legitimize their rule by invoking gods into physical form as their rulers, or are held in control by powerful sorcerers. This would draw on an article by Jenell Jaquays published in Dragon magazine under a different name, titled "When Gods Walk the Earth", in issue 144. I could probably also do this setting in GURPS with a very small amount of work, or maybe using Hârnmaster with a bit more work.
- Fantasy Wargaming: The Crusaders - Mainly, this would be a way to both show off and develop the FW game system. The game would be centered on a group of characters who have gone to join in the Third Crusade behind Richard the Lionheart. It would need at least six players, though, and a couple of the characters would be pre-gens.
- Realms of the Unknown: Tribes of the Volyet - This would use the maps of my Middle Sea setting, though not the "things I know" about that setting. In this campaign, the Long Sea (not the Middle Sea, which is to the east of that map) is renamed as the Volyet, with the players controlling clans on the eastern shore of the Volyet Sea. I have some events in mind, obviously, but the first part of the campaign would be the players getting used to the system and dealing with each other and some of the NPC clans in the region.
- CORPS: Deindustrial Future Dark - This would be the more realistic version of my Deindustrial Future setting. In this one, magic and such is scaled way the heck back, to the point that they are hardly discernible in the setting. No super gunslingers, no spirits, no alchemical potions. At least, not in the same sense as the GURPS version I am running now. I could also run this with GURPS, but I like to find reasons to use CORPS.
- Top Secret: Cyberpunk Shadows - Near-future using the Top Secret rules. There are some basic spaceflight rules in Dragon magazine, along with an article on lasers in Top Secret, and it's not really all that difficult to come up with stats and rules for other futuristic technologies. I haven't really thought through what I'd actually do with it yet, but it's an idea that keeps pushing itself on me.
- Chivalry & Sorcery 2E: Denizens of the Pale - Another one that mostly exists to showcase a rules set, and also the historical setting, this campaign would have the players as Anglo-Norman settlers in the Pale in Ireland in the early 13th century. They would have to live with the surrounding Irish people, as conquerors or neighbors.
And, you know, I have still more campaigns in my head. If there's interest, maybe I'll write down some more.
