I used AI to create an entire TTRPG game. Here’s where it actually helped.

I recently finished a 200+ page Lovecraftian 5e campaign setting and used AI throughout development, not just for text generation.

The most useful applications ended up being research support, playtesting, probability analysis for mechanics, editing, art development, and helping me iterate on GM-facing tools. The biggest lesson was that AI worked best when I treated it as a collaborator and accelerator, not as something that could replace design judgment.

I’d be interested in comparing notes with anyone else using AI for gaming and TTRPG development, especially where you’ve found it genuinely improves the finished product versus simply making production faster or less expensive.
