I need to know which systems use the Cthulhu Mythos. Could you give me a list?
Please give only systems that specifically reference the Cthulhu Mythos. For example, don't bother listing Escape From Tentacle City: tentacles don't make it Mythos. Similarly, don't give me minor references: don't list, say, Paranoia, just because a Paranoia scenario once mentioned Cthulhu.
Also, don't list all the different Call of Cthulhu settings: don't, for example, list Cthulhu Invictus.
Everything else - CthulhuTech, UnSpeakable, Trail of Cthulhu - is fair game. I'm particularly interested in little systems I haven't heard about.
(And this is Community Wiki, of course.)
