I've run a couple of sessions of City-of-Mist on Discord.  I'm not sure how it would translate to an asynchronous method of gaming...  and I'm not sure there's even the interest in it.

So...  Is there any interest?

I'm always interested in learning a new game

I am always interested in City of Mist

I've had the book for a couple of years but never had the chance to play so would be definitely up for giving it a try.

Interested but uncertain I have the time to commit.  If not would definitely like to lurk as I've also had the main book for years and never found an opportunity to play.

I have run the published campaign twice now (on my third run and it continues to go well). The campaign is one of the best published - rivaling classics like The enemy Within for Warhammer FRP and 'Masks of Nytharlatotep' for Call of Cthulhu.

It's a great game...highly recommended.
