The Cthulhu pack works well.
I play w the Lovecraft Storyteller AI on Rough difficulty (2 less than max). I use some QOL mods that I will post, nothing changes the difficulty but now pawns will repair, haul on their way back, small stuff.
The first game I didn’t Prepare Carefully, and rolled randomly until I got a reasonable spread of skills in my initial three. I decided to be super Lovecraftian and picked a cool coastal swamp. It was the swamp that killed me - we didn’t last past the Summer.
The biggest issue was skill distribution. I only had one person with good cooking and construction - and they were the same person. All three pawns had food poisoning almost continually, and when the main guy was down he wasn’t cooking. Also, combat skills were poor and they almost always took damage from even melee raiders. That meant more downtime for healing, and when that one pawn was down nothing was getting cooked.
The lowlight was running out of all food, with the cook unconscious in the medical bed. The one pawn with a reasonable shooting skill went into the jail and executed the prisoner. He dragged the body back to the freezer and then played chess. I ordered the other starving pawn to eat the corpse - but they got lucky with a turkey wandering across the compound and ate that.
I managed to rebuild from there for a bit longer. The end finally came when a solo raider with a poor rifle fought the three wounded and food poisoned pawns at the same time as a rabid wolf attack. One pawn was standing by the end - the main cook. He tried to rescue the other two but they both bled out as he slowly dragged them to the medical beds.
After they died he went berserk and attacked the dog. The dog won.
The next game I Prepared Carefully and setup a Call of Cthulhu-ish starting trio of a sherif, an old librarian (“Lore Master”?) and a young chef. They have reasonable skills and I made sure there were backup skills. Instead of swampy cold New England they are starting in the coastal forests of the Pacific Northwest. Let’s see how long they survive!
