Yesterday, I was perusing the used section of the FLGS near my house when I chanced upon a battered copy of The Book of Crypts for three bucks. This is an old Ravenloft supplement of short adventures, nine in all. I grabbed it, thinking I would adapt them to my Gothic Earth Ravenloft campaign to use as interludes between the modules in Masque of the Red Death.
...I read the first one this morning and it was fucking terrible.
If you are writing an adventure and you include a phrase such as "No matter what precautions the PCs take, she is still abducted..." Stop writing. Stop writing and don't start again until you come up with a better idea that rewards, rather than disregards, cautious and clever preparation on the part of your PCs. Seriously.
Also, if your bad guy holds someone hostage, and then moments later admits he has no intention of killing his hostage, prepare to have the rest of his monologue interrupted as the PCs jack him.
Hopefully the other eight won't be as terrible, but I'm starting to think that all 90's era TSR modules are just inherently terrible, Ravenloft or otherwise.
