Right now my big “one day” campaign wish is to do a Sword and Planet campaign.
Consider:[sblock]
If I run another 4e game it will probably be Dark Sun.
My unsolicited tip for running Dark Sun: Think
Barsoom, not D&D Survivor in the desert.
Yep, Dark Sun, was Sword & Planet.
I personally thought the 4E Dark Sun was the best version of it so far. The setting and rule-set really meshed. If I ever play/DM a 4e game again, that'll probably be my choice too.
You could run Sword & Planet in 5e, but it'd be a stretch, most of the sub-classes cast spells, or at least use some sort of magic. The forthcoming Mystic could help, since psionics are much more S&P-appropriate, but Monk, Ardent, Battlemind, & Psion could help even more. Besides, most characters in that genre would be martial. Slayers, Weapon Masters, Thieves, Rogues, Scouts, Hunters, Assassins, alien Berserkers - heck, John Carter was the eponymous
Warlord* of Mars.

Oh, the sincerest form of flattery, thank you so much.
I actually submitted Seven Cities to that 'Setting-Search'/Eberron-promotion-stunt they did back in 2002. The other one I submitted, Cinnephar, I went on to actually run (the only 3e campaign I ran, actually, and it was very much inspired by the 3.0 ruleset - a lot of work, but fun).
Just remembered another one. This is in the No Particular System game engine, because nothing really fits, which I suppose contributes to my never running it. That and I doubt I could ever find interested players.
The set-up is that the PCs are a group of young people who have grown up together. In fact, they are the youngest people they know. They're each the only child of a long noble line living on adjacent estates, with no others around, the tenants/peasants/slaves/whatever working those estates are all 50+ years old. Each of their manor houses contains a library filled with books, all written in the same language (represented by English, of course, but not really English - 'common' or 'Standard,' say). All are written in the style of first-person accounts, biographical novels and the like. You have no idea which are history, which are fiction. The library in your manor house consists of /every book you, the player, has ever read/, short of boring old technical manuals and textbooks (and, heck, novelizations of every movie/tv-show/whatever, for good measure). Among each of your family traditions is a 'secret' style of swordsmanship (not really secret, you guys spar with eachother all the time) and a 'family bible' showing dozens of generations, that filled up before your great-grand-parent's were born (and there's been no paper available - just slates & chalk - since long before that), so you have an oral history back a few generations, that you just kind of assumes picks up where the family bible ends. There are no dates (at least, that make sense) on anything, not the books, not the family bibles, nothing - everyone goes by seasons. Each fall, a taciturn old man poles a barge up the river to collect your families' taxes (which are pretty light, just produce from your estates), your only connection to the outside world. This year he hasn't come.
The farthest you've ever been from home is a stone bridge a full summer's day walk down river. You figure it can't be that much further to the city the old man delivered your taxes to, so off you go to re-establish contact...
The final conceit of the campaign is that each player picks a book that his character believes is a true history.
They'll find out which, if any, of them is right by the end of the story.
