Didn't Philip Jose Farmer write a series with this theme? I think I picked up the first book, but I don't think I ever actually read more than a couple of chapters (misplaced it for a few months, and never got back to it).
Sort of. He had a series entitled
The Dungeon but it wasn't exactly about a dungeon world. I've only read the middle books, never the first two or last two, but the concept seemed to be that The Dungeon was a big game between two master races (the Ren and the Chaffri, I believe) and conducted on multiple worlds or in vast spaces within a planetoid that simulated entire worlds closely enough as not to matter. Each 'level' of the dungeon was a world unto itself with an exit hidden somewhere. I think the initial level(s) were actually dungeon-ish before he branched out. One was a jungle world with dinosaurs, another was mostly covered in water, another was an urban wasteland.
People got sucked into this dungeon at the whim of the Ren and Chaffri from all over time and space. Most of them were somehow related to the main hero of the story, Clive Folliet (his quartermaster from the Navy, his great-great-granddaughter, his brother) but there were others that were apparently unrelated. A dog-like alien guy and a teenage phillipino sailor from the 1600s being the ones I remember.
I ran a campaign once that was partially based on
The Dungeon.
The other thing that comes to mind on the topic of indoor worlds that I'd like to run games in is Tad Williams' Otherland series. The whole thing could make for an interesting d20 Modern/Future campaign and I can't really describe it without giving away the whole secret plot but it's a great series and well worth a read (book 1 is
City of Golden Shadow for anyone interested).
In any case, there's a world described in those books that's entirely contained in a house. The rooms are, mostly, vast (some have weather systems or streams running through them) and others are normal sized, but the whole place is one big house. If you find your way to the roof you can look out at a normal sky but a labrynth of gables, towers, turrets, and sloping roof surfaces stretches off to the horizon in every direction. People in the house have lived for generations and haven't ever found an exit. I've considered running a game in such a setting but I'm not really sure where I'd go with it beyond the novelty of the setting itself.
