The investigator thing is a red herring. It's the generic term in
Call of Cthulhu for Player Characters, same as "Keeper" means GM. My memory of both the Civilian and Military scenarios I've read from the CR site is that you could substitute the term "Troubleshooter" quite easily. There's an element of investigation in them - but there's an element of investigation in
Steading of the Hill Giant Chief, and frankly its hard to do a modern or futuristic scenario that DOESN'T pose some sort of mysetry / conundrum for the characters to solve...
Now, having said that, I'm really note sure ANOTHER variant time period for CoC is a good idea as a BRP supplement. What BRP needs is settings that stand on their own, not that borrow from Chaosium's other line. In that regard, I quite agree that "de-mythosing" CR is the better approach. In fact, I'd go further, and up the Alastair Reynolds (one major plot thread in
Revelation Space is about an archeological investigation) / Ken McLeod (
Newton's Wake features "combat archeology") influences.
What I'd like to see is a)
Cthulhu Rising (and
Cthulhu Invictus) released as proper
Call of Cthulhu supplements / variants as
Cthulhu Dark Ages was and b) at least one full blooded SF setting for BRP from Chaosium (and I think John Ossaway would be the ideal chap to write it...).
But I'll settle for a de-Mythosed
Cthulhu Rising for BRP.
