Image: Fork Dev\n\nA solo game developer has built every 3D model in his upcoming Steam game without modelling a single one by hand. Every crab, seagull, palm tree and dock post in *I Just Wanted to Fish* was made by a Python script that Claude wrote and ran inside Blender, according to [a case study published on October 14](https://www.mcp-for-blender.com/creations/case-studies/i-just-wanted-to-fish/) by the makers of MCP for Blender, the free plug-in that lets AI models drive the 3D app.\n\nThe developer, who goes by Fork Dev, posted a clip of the game on X on October 3 with a caption any Claude user will recognise:\n\nThis is what 100% of Opus 5.5 weekly usage looks like\n\nAll models and animations made with blender mcp\n\nPlayable Demo Soon at:[store.steampowered.com/app/5350560/I_Just_Wanted_to_Fish/](https://store.steampowered.com/app/5350560/I_Just_Wanted_to_Fish/)\n\n[October 3, 2026](https://x.com/ForkedPush/status/2106313584829431901)\n\nThe clip has more than 125,000 views. The game, a cosy top-down fishing adventure, is listed on [Steam](https://store.steampowered.com/app/5350560/I_Just_Wanted_to_Fish/) for Windows with a release window of the fourth quarter of 2026 and a free demo promised soon.\n\n## From first commit to island in nine days\n\nFork Dev has used Unity for five years and shipped games on Steam before, but modelling was always his least favourite job, and his Blender work had never gone beyond simple shapes. In mid-September he heard Claude could build models in Blender and tried a beach with an ocean. A week later he started a fishing game.\n\nThe first commit went in on September 24. By October 3 the island had a rigged and animated fisherman, crabs, seagulls that steal your catch, fish, coral reefs, a stilt hut with a dock and rowboat, seven kinds of palm, a day and night cycle, menus and ten languages. The Steam page now lists 14.\n\n## One Claude Code session, two editors\n\nA single Claude Code session drives both Blender, through [MCP for Blender](https://github.com/ahujasid/mcp-for-blender), and the Unity game engine, through a separate Unity MCP connection. Fork Dev does the game and level design and plays every build; Claude writes and runs the scripts.\n\nThe crab shows how it works. Fork Dev sent two photos, a doodle and a four-sentence brief: crabs that wander by the water and dash into the sea or a burrow when startled. Claude built the crab from 40 parts, gave it 42 bones, painted three colour variants and animated **18 clips**, each step its own script, then set it up in Unity. Fifty-three minutes after the brief, crabs were walking on the beach. After two rounds of notes from Fork Dev (too many crabs, burrows too dark), the finished build was done in under two hours. Because every asset is a script, “bigger claws” means editing a number and running it again.\n\n## An art style built around the limits\n\nThe case study is frank about what this approach can’t do. Scripted modelling can’t produce complex smooth shapes such as a realistic face or an anime-style character. So Fork Dev built the look around simple geometric shapes, painted textures and ink outlines: his fisherman’s face is a dark shadow under a straw hat.\n\nIt joins a growing list of games made with Claude, from [a Pokémon Red rebuild with no image files](https://madrobot.blog/2026/09/28/claude-opus-5-5-rebuilt-pokemon-red-one-prompt-no-image-files/) to [Yuji Horii’s 30-minute detective game](https://madrobot.blog/2026/10/13/dragon-quest-creator-yuji-horii-claude-ai-detective-game-30-minutes/), while Epic Games has [told its Disney game team to let Claude write the code](https://madrobot.blog/2026/10/12/epic-games-ai-first-disney-marvel-star-wars-shooter-claude-tim-sweeney/).\n\n## “I keep running out of weekly limits”\n\nFork Dev [shared the game on Reddit’s r/aigamedev](https://www.reddit.com/r/aigamedev/comments/1x5w5pk/i_made_this_cozy_fishing_game_solo_with_claude/) on October 14. He put the project at “around 200 hours”, using only Opus 5.5 at its highest effort setting on a monthly Max plan, and said the weekly limits were the main problem, the kind of drain [our guide to making Claude Code limits last](https://madrobot.blog/2026/10/07/claude-code-burning-through-usage-tokens-how-to-make-limits-last/) is about. He said he started straight after Opus 5.5 came out because earlier models weren’t good enough, and has pulled “lots of all nighters” since.\n\nHis prompts aren’t short either. He said he gives Claude lots of reference images and doodles with about two pages of prompt, usually needs around three more passes to get an asset right, and credits Unity’s lighting for much of the look. He also said he opened the Reddit account because other accounts had been reposting his clips, some of them as adverts for AI tools he doesn’t use:\n\nOther posts on reddit are stolen from my X content... I created this account to fix that problem.\n\nFork Dev, on Reddit\n\n## Why it matters\n\nMost AI game demos stop at code; this one hands the 3D art, rigging and animation to Claude as well, the part of game making that usually needs a specialist. If *I Just Wanted to Fish* ships and players like it, it will be one of the first commercial games whose every model was written as code by an AI.\n\n*Sources: [MCP for Blender, “Launching a game on Steam with MCP for Blender”](https://www.mcp-for-blender.com/creations/case-studies/i-just-wanted-to-fish/); [Fork Dev on X](https://x.com/ForkedPush/status/2106313584829431901); [I Just Wanted to Fish on Steam](https://store.steampowered.com/app/5350560/I_Just_Wanted_to_Fish/); [MCP for Blender on GitHub](https://github.com/ahujasid/mcp-for-blender); [Fork Dev on Reddit](https://www.reddit.com/r/aigamedev/comments/1x5w5pk/i_made_this_cozy_fishing_game_solo_with_claude/).*", "url": "https://wpnews.pro/news/a-solo-developer-let-claude-build-every-crab-gull-and-palm-tree-in-his-steam", "canonical_source": "https://madrobot.blog/2026/10/14/solo-developer-claude-blender-mcp-every-3d-model-steam-game-i-just-wanted-to-fish/", "published_at": "2026-10-14 19:25:00+00:00", "updated_at": "2026-10-15 00:15:13.587723+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "generative-ai", "ai-products", "developer-tools"], "entities": ["Fork Dev", "Claude", "Blender", "MCP for Blender", "Unity", "Steam", "I Just Wanted to Fish", "Claude Code"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/a-solo-developer-let-claude-build-every-crab-gull-and-palm-tree-in-his-steam", "markdown": "https://wpnews.pro/news/a-solo-developer-let-claude-build-every-crab-gull-and-palm-tree-in-his-steam.md", "text": "https://wpnews.pro/news/a-solo-developer-let-claude-build-every-crab-gull-and-palm-tree-in-his-steam.txt", "jsonld": "https://wpnews.pro/news/a-solo-developer-let-claude-build-every-crab-gull-and-palm-tree-in-his-steam.jsonld"}}
