What are the best free AI game development tools?

Flocci AI Tools lists 3 of them, ordered free tiers first: Convai, Inworld AI and Rosebud AI. Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.

Which of these are completely free?

None of these are marked fully free — they are freemium, trial or paid. The Completely Free AI Tools collection lists the 115 entries in the catalog that carry no paid plan at all.

How is this list ordered?

Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
