Huge iPad tilemaps - single-file world editor with chunk streaming

Huge iPad tilemaps - single-file world editor with chunk streaming targets a $480M = 4.0M creators x $10/mo ARPU x 12 total addressable market with low saturation and a year-over-year growth rate of 10-18% annual growth as mobile creation and indie game dev segments expand.

Key trends driving demand: Mobile-first creation -- more artists demand full-featured iPad workflows rather than desktop-only tools, increasing demand for powerful iPad-native editors; Indie game growth -- more indie developers produce tile-based games, increasing need for map tooling that exports to engines; Cloud collaboration and sync -- expectations for cross-device continuity enable single-file cloud-backed world maps; Hardware upgrades -- modern iPad SoCs and storage make streaming/chunked editing technically viable on-device.
