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]

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.

Dragon Age, I really love the lore. Hopefully the new one won’t disappoint.

Also Wheel of Time has a really nice worldbuilding.

DrakeNier series: Starting by red dragon falling from sky in 2000s. Through guy in medieval, postapocalyptic 3400s trying to save his sister. Ending on androids in maid suits fighting a war against machine lifeforms and preparing Earth for return of humanity, in 11945.

Also I didn’t tell about origins of the dragon, because I haven’t played Drakengard series yet.

Disco Elysium.

At first, I thought it was nothing more than a parody of Europe. But then I started talking to the corporation rep on the boat about the world you’re in and holy shit. It’s nuts how they give you all this insane exposition about how the world works, how physics are different, how there are literal swaths of VOID called The Pale that separate the isuldas and is described almost the same as how crossing space in Warhammer works. Like you need special tech and special protective suits to not lose your mind or be erased, and even then you want to limit your time in the pale. There are fantastical creatures that exist (you may even see one depending on how you play), incredible technologies, and even differences in real tech that become fantastical in the way they are different (like how they have something like the internet, but is dependant on using an actual phone to talk to an actual operator).

I am so dismayed at the fact there are like 3 or 4 Disco Elysium spiritual successors in development right now, but NONE OF THEM are actually going to be set in Elysium, because the world of Elysium would be amazing to continue to explore. 😮‍💨

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

Kipo and the World of Wonderbeasts is entirely underrated in so many ways. Worldbuilding is one. Music is another.

The Expanse or First Law

I’ve enjoyed the world building of the Warhammer 40k setting.i started out with the models in high school and moved into the books to not have to deal with sweaty, agro nerds wanting to rules lawyer the game into no fun. So many interesting stories set in the grimdark universe, and a ton of great characters to follow.

Peter F Hamilton is another good one, though his world building is rather dense. Hell tell you all about how the roads on some alien world are enzyme bonded concrete or how the magic paths traverse entire worlds and systems. Definitely not for everyone, but the audiobooks are great (John Lee has such a soothing voice) and I’ve heard them so many times they make a great media to fall asleep to when I’m traveling.

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.

LotR - it’s really fucking hard to top especially when Tolkien was pioneering the field.

It was a short story, but I really like Faun by Joe Hill. The way the two worlds interact was really fun, and I’d love to hear more about it.

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.

Magic: the Gathering.

It churns out a ton of unique settings and ideas for worlds.
