The Ratchet & Clank Reverse Engineering Project is the name I choose to describe the collective ongoing effort of reverse-engineering Ratchet & Clank games.
This work, along with documenting prototypes, cut content, etc, is mainly conduced on the Game F*ckery Inc. Discord server (invite-only).
The ultimate goal would be a complete rewrite from scratch of the engine, but who knows when (or even if) it will be done.
