It's a great system when your focus is storytelling, it's really fun and the Tags system gives freedom of choice to the players like very few other games. That being said, the Moves players have available give restrictions on what players can actually do (This must be why they are removed on Legend in the Mist, another game system from Son of Oak), and you need to get creative on that. The Logos/Mythos "balance" system is another great part of City of Mist, since it helps you to organically mix the urban and mundane aspects of life, with the fantasy provided by the Mist. Lot's of resources for GMs and they even have a discord for when you're looking for other players.

Great GM, really helpful on character creation for players who have no idea on how the system works and explaining the rules during gameplay, very good at setting the game pace, and at setting the mysteries that the players must resolve.

Very patient and fun to play with, great and knowledgeable GM, and performs both the npcs and the setting in a very amusing way.
