Hi,
I've just purchased 7th edition for CoC, Not having played any of the previous versions (so, no baggage) for use with Cthulhu Britannica from Cubicle 7.
There is some good material there it has to be said.
Looking at the supplement books and again Chaosium have some good stuff for various locations around the world I notice a couple of to my mind glaring omissions.
What about Paris and Berlin?
In the 1920's surely they would be absolutely banging places to set a CoC campaign?
I wonder if they could come out in the future
Thoughts.
