While reading through the published adventures I noticed a certain trend there. Once upon a time WFRP scenarios was about characters solving problems and then getting accused of them. Now it seems that behind every scheme there's a "monster of the week". The scenarios themselves are quite good or at least have some good and usable ideas but the endings are quite disappointing. No matter what the characters do there's always someone lurking behind the scenes to act as a "boss monster".
Eye for an Eye - Daemon or beastmen - depending how you look at it. Still this one is can be lead to.
Edge of the Night - Skaven greyseer. "Hello! We're are to socialize with nobles and get a patro... Holy Sigmar! That's a big rat ogre you have there!"
Horror at Hugendal - Bigger daemon. As if solving a simple mystery behind a disease isn't enough a daemon just arrives to town!
The Gathering Storm - So they guy we were fighting for suddenly turned out to be the guy we were supposed to fight against! What a twist!
The Witch's Song - Dark elves and Kraken! Witch hunting at a smelly swamp turns into a full scale skirmish with an army of dark elves!
I think you get what I meant...
So what to do with this? I understand that some players and GMs like this. And it's okay. Once in a while. As a GM I couldn't dream of running a series of adventures where the players have to realize they just couldn't have solved the problem as it was in the first place. For me that would be a big turn of.
Now this could be easily turned into a bigger campaign.
Take the Edge of Night and the social aspects of it - characters have to do certain favors for nobles and they could as well be smaller scenarios. Aschaffenberg hires the group to inspect his manor. After the players destroy the Cult the surviving members become somewhat annoyed and plan to ruin the whole thing going on in Ubersreik. When the nobles go to party replace the Skaven with sneaky cultists and you have a more plausible revenge scenario in your hands than a Greyseer coming to town with a handful of minions just trying to "I dunno, maybe killmurdermutate a couple of slavethings".
