Forest of Deceit is intended as the introductory or "set up" module to a series of interlinked adventures that flesh out an area of the setting. According to the module, there are three more "chapters" or adventures for this setting yet to come. This can be good or bad for GMs, because if the adventures don't catch on (or there are long delays between each release) then that can adversely impact the campaign.
While designated as an adventure, what Forest of Deceit really is would be a series of short woodland encounters, intended to be used as the adventurers travel to the city of Namar (to be outlined in an upcoming adventure). The encounters are interesting, and are linked thematically by being in a wooded area. There's nothing that really ties these encounters to the Forest of the title, so a GM could easily drop them into any sort of woodlands encounter. As a matter of fact, I may use one or two of these encounters in my own Swords & Wizardry Whitebox campaign.
My main complaint with this adventure is that a lot of pages are wasted by reprinting the monsters. Each encounter is self-contained, with its own monster write ups, but each of these write ups is then reprinted in a six page bestiary section. Those six pages could have been better utilized with another encounter or two. And while speaking of the monsters, I have to say that I found the "shorthand" used to give stats to the monsters in this module a bit confusing, since they don't exactly sync up to any of the old (or new) school fantasy games. Since most of these monsters are fairly common, finding write ups for them in your system of choice shouldn't be hard, but I think that I would have preferred if they had gone with using the stats from an existing Old School game (anything from Castles & Crusades to Labyrinth Lord to Swords & Wizardry) rather than this approach. The OGL has made it so much easier to create compatible materials for so many games that this would have been so much easier to make something compatible than to come up with yet another way to reinvent the wheel of monster write ups.
Is this module worth the money? Well, that's a tricky question. I'm sure that someone will find a use for the material in this module, so for some that answer is an obvious yes. However, at $7.50 (for the PDF) for 34 pages of text and front and back covers, I am not sure if this is worth the money as it is. I think that this module could be much more successful if the encounters from it are integrated into a book with more of the Namar setting information integrated. That way GMs and players won't be left hanging when they finish these encounters but still do not have the city that is supposed to be their destination. With these couple of flaws, I can see this PDF being worth more in the range of $2-$3, rather than the $7.50 that it costs. There's too much introduction and not enough follow up to really make this worth the price of admission.
Hopefully this module does not set the tone for other Eldritch Enterprises modules. I would like to think that Ward and Mentzer have a lot more experience at setting up these sorts of modules, but only time will tell.
