Show HN: Open-world text adventure played through AI agents

Eremoterra lets you pick any parcel of Earth, hand a prompt to an AI agent such as ChatGPT, Claude or Cursor, and have it describe and build on that patch as if no one had ever lived there. Trying a patch is free for a night; keeping it costs USD 1, a price that rises about 0.7% each time another 0.1% of the planet's 233,280,000 parcels is claimed and doubles every 10%. Patches carry a server-rendered chronicle of events, can be shared by link without an account, and can be populated by a people you define.
