Castle Story

Lore & Background

Castle Story was first announced in December 2011, when Sauropod Studio was a team of two people. The studio was formally founded as a company on 24 April 2012 by François Alain, Germain Couet, and Benoît Alain. A crowdfunding campaign launched on Kickstarter on 27 July 2012 sought US$80,000; this goal was reached and exceeded within five hours, concluding after one month with $718,571 pledged. Sauropod credited Markus Persson, creator of Minecraft, for publicly approving the game and leading the campaign to success.

Reader's Guide

Castle Story is notable as the debut title of Sauropod Studio and as a successful early Kickstarter project that raised $700,000 against an $80,000 goal. The game's development spanned from its 2012 crowdfunding to its full release in August 2017, with a lengthy early access period on Steam starting in September 2013. Its significance lies in demonstrating how indie studios could leverage crowdfunding and early access to fund and develop a sandbox strategy game. The game's post-launch support was limited, as Sauropod shifted to bugfixes and developing post-launch content. The studio's subsequent troubled development of Mirador and eventual layoff of all 20 employees in September 2019 highlights the financial risks indie studios face even after a successful debut.

From Classroom to Global Hit

What began as a coursework assignment at the Gotland campus of Uppsala University in Sweden would eventually become one of the most successful indie survival titles of the 2020s. The team behind Raft, operating under the studio name Redbeet Interactive, uploaded a playable prototype to the indie platform Itch.io in December 2016. That early build caught the eye of several YouTubers, and the resulting buzz gave the small group the confidence to treat the project as their full-time occupation. The studio grew from three developers to seven as they refined the game, and Axolot Games stepped in as publisher. Raft entered Steam Early Access on 23 May 2018, spending nearly four years receiving steady content updates before the complete version shipped on 20 June 2022. Console players were not left out for long: PlayStation 5 and Xbox Series X/S ports arrived on 4 December 2024, extending the raft's voyage to living rooms around the world.

The Survival Loop

Raft drops players onto a four-panel wooden platform in the middle of an endless, shark-infested ocean. The core loop is deceptively simple: swing a hook into the current, reel in whatever debris the wind has pushed by, and use those materials to grow your floating base. Planks, palm fronds, and salvaged plastic feed into a research table that progressively unlocks more complex blueprints, while a smelter turns raw ore into usable ingots. Beyond building, players must keep hunger and thirst meters above zero by farming, fishing, hunting, and purifying water. A cooking pot or juicer combines ingredients into meals that grant bonus status effects. The threat is constant. Sharks circle the raft, lunging at anyone who slips into the water and gnawing at planks, though a spear or bow keeps them at bay. Seagulls add a quieter nuisance, pecking at crops unless a scarecrow diverts them. The raft becomes a canvas: walls, staircases, roofs, ziplines, and collection nets transform the platform into a sprawling mobile home. Multiplayer supports up to ten friends with cross-platform play and voice chat, while a creative mode strips away survival pressure for pure building.

Story Islands and the Apocalypse Narrative

While the open ocean provides an infinite sandbox, Raft's narrative spine runs through its story islands. Crafting a radio receiver from batteries and antennas unlocks a radar that pins nearby landmasses on a map, and entering four-digit codes steers the player toward these larger, puzzle-laden destinations. Each story island can consume several in-game days of exploration and is dotted with discoverable notes, voice logs, and non-player characters whose dialogue peels back the world's backstory: a corrupt military general has imprisoned survivors, and the overarching goal is to free them. These NPCs also become unlockable character skins once spoken to. The islands sit within a broader open world where smaller and larger landmasses offer trees, wild fruit, paint flowers, metals, and clay in shallow reefs. Trading posts on the bigger islands accept recycled trash cubes in exchange for useful goods like fishing bait, and players can capture livestock—cluckers, goats, llamas, and bees—to bring back to the raft for ongoing produce. Hostile wildlife, including screecher birds, warthogs, and pufferfish, guards these shores. Completing every story island unlocks the final tool tier and triggers the game's ending, though the ocean remains open for continued drifting and building.

Critical Acclaim and Commercial Milestones

Critics largely celebrated Raft for the elegance of its design loop, the satisfying sense of progression as the raft grows from a few planks to an elaborate multi-level structure, the depth of its multiplayer experience, and the narrative texture of its story islands. A minority of reviewers noted that the opening hours felt slow before the crafting tree really opened up. Commercially, the game's trajectory was remarkable. The full release on 20 June 2022 made Raft the best-selling title on Steam for two straight weeks, a rare feat for an indie survival title. Its December 2024 console launch on Xbox Series X/S was similarly strong, placing it among the best-selling indie games on that platform. By 2024, cumulative sales had crossed the five-million-copy mark, a number that underscores how a student project born at a Swedish university campus managed to capture a global audience. The game also supports community modding through an external mod loader and the RaftModding download site, giving players additional avenues to shape their own experience on the water.
