What's he smoking? There is no shortage of short "module" adventures, even without going to third-party publishers. If you do go to third-party publishers, you can quickly drown in short adventures.
- The preponderance of big campaign-length adventures like Curse of Strahd (which, for the sake of brevity, I'll call Epics) is bad for the hobby, and shorter adventures (which I'll call modules) would be better.
