I really love Jack Vance’s world building. His Gaean Reach setting gives an endless variety of cultures, customs and beliefs. And the Dying Earth novels formed the basis for magic system of DnD.

But the real treasure is in how he can let these worlds come alive with his descriptions. Often he would spend a whole paragraph describing something that will never be part of the story but manages to perfectly set the tone of the local atmosphere.

I grew with these books (thanks to my dad’s impressive personal SF library) and they’ve always managed to spark my imagination like no other book.

serious answer: Discworld. every storyline starts out completely separate but through the years they wove together into a world rushing headlong into a new age.

The Expanse or First Law

I consider lore and worldbuilding to be related but different concepts. Lore is the details of your world, worldbuilding is the way you deliver those details.

My favorite example of worldbuilding is The Dark Crystal, both the film and series. The lore is standard fantasy stuff, but the intricacies of the world are so rich and they unfold so naturally. It felt like a real world, and I felt like very little of what I learned about that world was simply narrated to me. The world was built through tiny details, interactions and observations, throwaway lines of dialogue, and effectively so.

Chinese xianxia and wuxia shows. I’m a brown person from the American southwest who grew up with mostly European mythology and fantasy stories. Learning about a very different world of myth and lore has been endlessly fascinating and exciting for me. I even homebrewed a ttrpg around it so I can share some of the cool concepts and stories I have learned.

The Elder Scrolls is probably the one I’ve had the most fun theory-crafting about, but I will admit that you have to pick and choose what to care about.

Also the old Wipeout racing games had a remarkable amount of background plot going on that was really pretty fun. The self-awareness to poke fun at Fusion’s poorly-received changes as being the in-universe result of megacorp meddling for mass market appeal gave me a good laugh, but you can piece together a surprising amount of the world from random references in team flavour text

One that just popped into my mind… The Culture Series. I really struggled to get into Consider Phlebas and must have restarted it three times before I got it. After I did, it was very difficult to not think about it all the time. I stopped when life got a bit busy so I do need to pick Excession up again, or restart since it’ll all be pretty fresh again by now.

MALAZAN

I’m only on the 5th book but the world building is Tolkien level of detailed. Writer Stephen Erickson is an anthropologist who brought he and his achaelogist friend Ian esselmont dnd world to written reality. Esselmont has books in the series too but not that far along yet.

It makes it difficult to pick up other books afterwards. Major caveat I didn’t know what the fuck was happening until the second book. Then it clicked.

Wonderful writer and world building.

The Foundation series by Isaac Asimov. Though, I guess what really hooked me was the idea that the future could be predicted, and guided toward an outcome that would benefit people. That, uh, doesn’t seem to fit with reality. But it sounds real nice ☹️

Right now I’m way down a Brandon Sanderson rabbit hole, so I guess the Cosmere? I’d say Stormlight Archive, but Mistborn is really cool because they’re set at the inflection points in the planet’s history. The first arc is excellent, and it changes the world. The second arc is set in the future, with mythologies based on the first arc and scientific progress based on secrets uncovered in the first. The changes in the use of magic are really cool. There’s a third arc planned to be set in the future from there.

But the Cosmere as a whole shares some core concepts and characters can move across it, and that comes into other standalone works like (3 of 4) secret projects and a bunch of other stuff.

Kim Stanley Robinson’s Mars series.

Just a breathtaking setting that begins with the first hundred settlers and traces the intrigue, terraforming, conflicts, and dreams of the colonists. It’s a sweeping epic written on a human scale.

The original StarCraft and Brood War. I’ve always hoped a movie would be made about the story/lore but hollywood doesn’t exactly have a good track record with turning games into movies.

BattleTech/mechwarrior. I think it started as a tabletop game? Lots of media came from it, and video games pop up every few years starting in 1989.

The series began with FASA’s debut of the board game BattleTech (originally named Battledroids) by Jordan Weisman and L. Ross Babcock III and has since grown to include numerous expansions to the original game, several board games, role playing games, video games, a collectible card game, a series of more than 100 novels, and an animated television series.[3]
