Pretty early, when they decided to set it in an entirely different world than the first game. Knowing that none of the things we did would be followed up on, no plot threads would be set "this is how it went officially", none of those actions would have their long term consequences played out, killed any hope I had. It became clear that Fen had let Sav codify his DnD porn campaign, taking the name of the beloved game and doing what he wants with it. And then increasingly seeing content that had been drafted for CoC Classic be reworked and bastardized for CoC2 put the nails in the coffin. And Savin has always had a different tone to his writing that I don't jive with.
