„Guests for Dinner“ is a pay-what-you-want, OSR-fantasy dungeon crawl that weighs in at 10 pages, 7 of them including the little OSR run-in-dungeon it is, as well as a quick guide to a nearby town, how and why the dungeon is what it is, and a small (half page) primer on „character-funnel-type play“.
The dungeon itself pretty much what one has to expect from such a limited format: it includes a total of eleven encounter areas, each with its own (rather) brief description. The map is functional and not a bad one, but I miss a scale or a size description. Not that it is overly important (there is a grid and every GM can easily decide upon the measures that fit his or her needs best), but if sizes were been mentioned somewhere in the module, I missed them.
That being said, the module has a horror touch to it that keeps it from being „just vanilla“. While me, as a „horror-film-friend“, had a lot „deja-vu“ during the read, I guess that this icing on the cake takes „Guests for Dinner“ one notch above the middle ground. You will for sure get a „been there, done that“ feeling if you are accustomed to contemporary horror films, but the fact that you have eaten a steak before will not change the fact that a nice piece of steak is a nice piece of steak. And the meat that is there is nice. Of course, the format means that you only get the general ideas and have to work on the rest of it, but the ideas are good and they are all -linked- into the background/synopsis of the adventure. A GM who wants to build up on what is there will have an easy time doing so.
The module may be used as a one-shot, as the start of a campaign or adventure group, or as a „one on the side“ thing that just happens to a group between other adventures. It seems to be excellent as a one shoot for one evening, as it literally drops the characters into the action right from the start.
All in all, I say give it a look and if you actually use it for an evening of entertainment, give some money, too.
