A powerful parameter editor with no coding required. Build custom entity types, tune balance, and change game characteristics in real time — then export everything to Unity, Unreal, or Godot as clean JSON and CSV.
Items in one spreadsheet, characters in another, quests in the design doc. Nothing is linked, and nobody can find the real numbers.
Changing one stat means digging through scripts and configs — a job for programmers, not designers. Iteration grinds to a halt.
Someone "fixed" the sword damage last week and nobody noticed. There's no history, so there's no way to know what changed — or undo it.
Design data lives in the docs; the engine reads its own format. Every sync is manual, slow, and full of mismatches.
IMSC is the fix: game data as structured, versioned entities — editable without code, referenced across the whole project, and exported to engines in one click.
No code, no schema files. Build new game entities with an intuitive visual editor — define the fields, types, and relationships that your game actually needs. Items, characters, quests, skills — anything you can model, you can manage.
All game parameters are stored in a structured form, with quick search and powerful filtering. Find any item, character, or quest in seconds — and see exactly how it relates to the rest of the project.
Apply changes to groups of objects combined into collections simultaneously, through a convenient batch-processing interface. Rebalance an entire weapon tier or update every quest reward — without touching them one by one.
Track edit history and revert to previous parameter versions at any time. Know who changed what, when, and why the numbers moved — so experiments never get lost and mistakes never stick.
The system automatically converts exported data from JSON and CSV files into your desired format, for easy integration with game engines. Export tuned values for Unity, Unreal Engine, and Godot — and PDF or Markdown for the team docs.
