Just a short review of Dungeon Delves. [Note while the link goes to amazon, I can't stress enough try to buy these kinds of things from your local game store. It's just good manners if not good fiscal sense.] It’s basically a series of decent to good one shots. 30 of them, 1 for each level. Most are pretty forgetable, once you’ve run and gunned them as they’re written you and your players will probably not remember them a month later barring something really cool happening outside the scope of the entry.
Where they have added value, if you’re willing to do the work, is each one has recommendations/ideas on how to increase the size of the encounter and make a longer than one session adventure out of it.
Each one has almost without fail the 2-3 fights and then a boss fight of some kind. Fairly standard procedure and formula really.
But, there are a good handful of new monsters, maybe 20 I would guess so that’s something.
All in all I’d recommend having it if there are times when you just don’ t have time in your schedule to keep one adventure ahead of the players (my formula). If you hit a empty spot because life got in the way of your fantasy and everyone wants to keep playing you can easily haul this book out and drop in a level appropriate encounter.
There’s also discussion in the book about using these as a tabletop mini’s game where the DM is in an adversarial position, kind of like Descent perhaps, and is actively trying to kill the players and the players are actively trying to kill the NPC’s so it’s more like a boardgame than a RPG game. If that interests you then the book will have added value.
