A Thing For Man To Not Know: Cyclopean

Since Age of Decadence is showing progress towards release, I thought now would be a good time to mention that it's not the only thing that Iron Tower Are up to. Cyclopean is a Lovecraft derived RPG set in Arkham and involving - oooh - things with tentacles, things man was not meant to know and extreme adjective abuse. It is Lovecraft, after all. It's clearly long way off, but here's some concept art and here's some of the in-progress 3D models. It's certainly a classic setting for an RPG, but always a tricky one. What sort of things would you have in a Lovecraft RPG? At least it cuts down on the books you're meant to read as in Lovecraft YOU SHOULD NOT READ THE BOOKS.
