Hello,
I just received word from Chaosium that we are authorized to use the new 7th Edition rules for Cthulhu: Strange Aeons.
So that settles that question!
We're getting the Kickstarter ready for approval so it shouldn't be too long now.
I do have a few more details. We have a stellar group of writers to bring C:SA to you. A. Scott Glancy, Robert Schwalb, Oscar Rios, Jeffrey Moeller, and Sean Molley round out the writers of the Core books. Yes, "books" because there's just too much information for one , so the game is being broken up into an Investigator's Guide (estimated 160 pages) and a Keepers Guide (estimated 256 pages) with little to no repetition of material.
We're ironing out the final outlines of the books now. Once it's finalized I'll post it here if there's an interest for it.
As always, thank you for your interest!
