Howdo one and all
Been a while since I ran Cthulhu, bout ten years or so. I recently ran the first of a five scenario arc that I've got planned. I'll post details of it in my journal over the next couple of days.
However the biggest problem I had was pacing San Loss. Being the first game I didn't want to drive anyone over the edge straight off, since plot threads were being laid and heck I wanted it to be a fairly laid back introductory game.
So the first big encounter was with the "Haunted House" (ok so it was alot less cheesey than that.....20 years of GMing experience have taught me a trick or two...but that was the basic premise). Que first san loss for the entrails of blood down the hallway. Followed up with more San loss seeing the Ghost, then the horrific murder scene, another for more horrific sightings of the ghost, and relealising what was going on in the whole scene I got the description just right and the players were hooked. But stopping and rolling the dice for san broke up the narrative and made me feel like my plot was at the mercy of some random rolls. i.e I was trying to steady build up of terror, which could have been thrown out of key by one of the pcs lossing it.
I did think that less rolls, but at significant points....entering the house and its distrubed atmosphere, seeing the murder (a high point in the terror), but not for events that didn't up the fear so to speak.
Another idea was fixed but small san loss for the horrific events which were not such high points of the story, and dice rolls as normal for the more dramatical significant moments.
