Thanks for running this! A very interesting experiment.
My impression is that this play style feels a little rushed, and the choices available made me think more of a 'choose your own adventure' book than a PbP rpg game. For the sake of speed, maybe roleplay and atmosphere suffer a little? Not a bad thing per se, just a very different style of play. I felt I was playing the boardgame 'Arkham Horror' rather than Call of Cthulhu, with a set list of possible actions.
ToC impressions after seeing it in play: it feels a bit like a boardgame, with the pools of points used like a currency. The non investigative abilities, with the rolls + bonuses made more sense to me than the investigation interactions, that become a negotiation between GM and players to 'buy' clues. It affects a lot the sense of mystery, for me? Knowing that there is definitely something hidden is not as intriguing as not knowing. But that's the pillar of the whole R. Laws / K. Hite premise...
I will give the rules another read, maybe I am not yet seeing the nuances.
For now, Melody bows with a flourish, and thanks you all!
