About This Game

World of ClaudeCraft is a classic-style micro-MMO that rebuilds the feel of the golden age of online RPGs — with an authoritative server and persistent characters, so the world is genuinely shared.

Nine classic classes done faithfully (Warrior, Paladin, Hunter, Rogue, Priest, Shaman, Mage, Warlock, Druid) with real vanilla-era ability kits, resources and spell ranks.

A hand-built world with a story: begin in Eastbrook Vale and follow the Gravecaller conspiracy north through Mirefen Marsh and up into Thornpeak Heights — three zones, ~60 quests, vendors, rare spawns, living overworld AI.

Group up for 5-player elite dungeons: the Hollow Crypt, the Sunken Bastion, the moon-cult Drowned Temple, and the Gravewyrm Sanctum finale — multi-phase bosses, add waves, class-split blue and epic loot.

Play with and against others: parties of five with shared quest credit and real group XP bonuses, atomic player trading, friendly duels, and the Ashen Coliseum ranked 1v1 arena with persistent Elo and a live ladder.

Authentic to the core: real classic-era formulas (armor DR, spell-hit tables with the level cliff, XP curve, rage conversion). Everything procedurally rendered and synthesized — timber towns, torch-lit crypts, animated water, painted spell icons, a full WebAudio soundscape, no stock assets.

The world is getting bigger by the day. Join the community!

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

World of ClaudeCraft is, unapologetically, a game built with AI — the name is a hint. We used AI in two ways, and we want to be clear about both.

During development, the game's code was written with an AI coding assistant, and we used AI generation tools to create some of the assets that ship in the game as ordinary, fixed files:

Sound: Most in-game sound effects and all spoken NPC voice lines were generated with ElevenLabs' AI audio and text-to-speech models. The written dialogue itself is authored by us; AI produced the spoken audio.
3D models: A small number of creature models (the "Drowned Litany") were generated with Meshy AI (text-to-3D).
Everything else is either created by the game's own code (the world, towns, terrain, water, weather, and the music soundtrack are all generated procedurally at runtime) or is licensed third-party art — CC0 model, texture, and HDRI packs plus a purchased commercial icon set. That content is not AI-generated.

Critically: no generative AI runs while you play. Every AI-made asset was generated once, offline, during development and baked into the game as a static file. The running game makes no AI or LLM calls, and none of your gameplay or personal data is ever sent to an AI system. The simulation is fully deterministic — the same inputs always produce the same result.
