Sci vs Fi
Ringworld vs Disc World
Larry Niven and Terry Pratchett both built impossible worlds on the page and dared readers to believe in them. Niven's Ringworld is an act of engineering faith: a structure 186 million miles in diameter, mathematically plausible, physically demanding, populated by people who are competent and technology that works across millennia. Pratchett's Discworld is its philosophical opposite: a flat disc on the backs of four elephants standing on a giant turtle sailing through space, populated by people who are magnificently, reliably wrong about nearly everything.
What most readers don't know is that Discworld owes Ringworld a direct debt. In 1981, Pratchett wrote Strata, a novel he described on alt.fan.pratchett as "as much a pisstake/homage/satire on Ringworld as, say, Bill the Galactic Hero was of Starship Troopers." The flat disc at the center of Strata was Pratchett's way of subverting Niven's ring: replace the hard science megastructure with a medieval comedy. Niven read it, said he enjoyed it, and apparently bore no grudges. That generosity matters. Out of Pratchett's satirical riff on Ringworld grew the entire Discworld cosmology — forty-one novels, a fully realized moral universe, and one of the sharpest satirical bodies of work the genre has ever produced.
Niven asked: what could humanity build, given enough time? Pratchett asked: what would humanity do with it? The answers are equally compelling, and equally necessary.
Winner: Draw
Thoughts: Whether you prefer the calculated precision of Niven’s universe or the whimsical chaos of Pratchett’s, there’s no wrong choice. Ringworld earns its place as a monument of hard SF imagination; Discworld earns its place as the genre's conscience. That one gave birth to the other makes a draw the only honest verdict.
Something Old
Red Thunder
by John Varley
"A race to Mars is underway — China's government program and NASA's best are neck and neck, and nobody's giving the edge to four teenagers from Daytona Beach, a washed-out astronaut, and his cousin, who may be a genius. But Jubal has built something extraordinary in his barn. With a device that shouldn't work according to any known physics, they decide to go anyway. The Red Planet isn't waiting for anyone's permission."
Red Thunder was published in 2003, a year after SpaceX's founding and years before private spaceflight had proven anything. Varley wrote the private-citizens-beat-the-government-to-Mars premise before it had any basis in reality. Reading it now, with commercial launch vehicles reshaping the industry, the novel lands differently — less like adventure fantasy and more like a prophecy Varley was too modest to claim. It won the Endeavour Award in 2004, sold steadily, and still gets overlooked in conversations about Mars fiction. Varley wrote it as an explicit homage to Heinlein's juveniles, but it has an edge and a Florida scrappiness that's entirely his own.
If you haven't read Red Thunder, it's highly recommended.

Something New(er)
Dungeon Crawler Carl
by Matt Dinniman
Amazon summary: The apocalypse has arrived — not with a bang, exactly, but with the entire surface of the Earth being stripped away and replaced by the first level of a dungeon. Coast Guard veteran Carl and his ex-girlfriend's cat, Princess Donut, are among the survivors dropped into a trap-filled, monster-filled, loot-box-filled labyrinth that also happens to be the most-watched reality show in the galaxy. Billions of alien viewers are tuned in. Sponsors are involved. There are achievement notifications. The dungeon goes deeper.
Review: Dungeon Crawler Carl is the best argument yet that LitRPG isn't a genre — it's a delivery mechanism, and what you put inside it matters enormously.
Dinniman's prose moves fast, hits hard, and has a comedian's sense of timing. The system notifications, stat screens, and loot drops that define the genre aren't decoration here; they're the satire. Every achievement pop-up is a punchline about how we've gamified everything, including survival. The writing is violent, frequently vulgar, and occasionally heartbreaking in ways that sneak up on you.
Carl is the kind of protagonist who makes bad decisions for understandable reasons and somehow keeps your sympathy anyway. Princess Donut, the cat, is not a gimmick. She is a character. That's all that needs to be said on that front, and no spoilers are required to make the point.
The standout isn't any single scene — it's the accumulating dread of realizing the dungeon's corporate architecture is not that far from systems we already live inside. Dinniman uses a blood-soaked game show to say something about exploitation, spectatorship, and what people will endure when the alternative is oblivion.
Self-published in 2020, picked up by Penguin Random House in 2024, six million copies sold across the series. The market figured this one out. If you haven't, now's the time.
Highly Recommended.
