Rick Swan reviewed Ravenloft Monstrous Compendium Appendix II: Children of the Night for Dragon magazine #206 (June 1994).[16] He commented on the proliferation of monster books from TSR and other publishers: "Role-players seem to have an insatiable appetite for monsters. The sound you hear is that of publishers scraping the bottom of the barrel for new ones."[16] Swan noted that Children of the Night, by William W. Connors, adds living brains, bardic liches, and half-golems to the Ravenloft roster. Reviewing this with two other monster books from two other publishers, he quipped: "They're all interesting, but I bet if I read you the descriptions, you'd be hard-pressed to tell which monsters belonged to which system.[16]
Trenton Webb reviewed Planescape Monstrous Compendium Appendix II for Arcane magazine, rating it an 8 out of 10 overall.[17] He commented that the book "has a great cover and it's a top read too" and that the artwork "isn't exactly exactly inspired but it does sport a coherence and consistency rarely seen in roleplaying books. There are no 'well it's a man's head on a chicken's body' Crimewatch photofit embarrassments'" found in many other monster books.[17] Webb noted that the text "goes out of its way to encourage adventurers to use this book as a foundation rather than a work of reference" and that most of the descriptions feature quotes to add flavor, "which normally involve the quotee being horribly killed".[17] He felt that the blend and balance of the roughly 100 creatures in the book was good, "with a lively mix of the lawful and chaotic, the mighty and meek" but noted that the book "does err slightly in favour of the more fearsome, more powerful creatures".[17]
Trenton Webb reviewed Monstrous Compendium Annual Two for Arcane magazine, rating it a 7 out of 10 overall.[4] He comments: "Serious work goes into bringing the beasties to life, but the crippling list format means they limp rather than leap (or crawl, or slither, or fly for that matter) from the page. A fault this work compounds by further tweaking the experience points system. A factor that's made all the more frustrating when it becomes apparent that the Monstrous Annual 2 dangles some delightful creatures before the referee's eyes."[4] Ramshaw appreciated one creature entry above all the others, naming the "star, without a shadow of a doubt" as the shambling umpleby: "Even without the Umpleby the Monstrous Annual 2 would be a necessary resource for all mainstream refs. With the shaggy-haired one, though, it rapidly approaches the essential."[4]
Trenton Webb reviewed Ravenloft Monstrous Compendium Appendices I & II for Arcane magazine, rating it an 8 out of 10 overall.[6] He noted that this product was a re-release of the first two Monstrous Compendium appendices for Ravenloft, in a single bound volume, and that Appendix I details "the variants, updates and unique monsters which lurk in the Demiplane's mists" while Appendix II "takes these new creatures and fleshes them out into full NPCs, expanding the descriptions in Appendix I".[6] He commented that as a reference book, "Appendix I does its job well enough. The true worth of the work, though, undoubtedly comes from the quality of Appendix II's creations" which "offer referees a varied and rich source of legends to drop into their tavern conversations or to add colour to campaigns". Webb concluded his review by saying: "All Appendices I & II offer DMs who own the old loose leaf versions are a few new piccies and the tidy new bound form, which is all well and good but hardly enough to justify [the price]. But for Ravenloft DMs who've been struggling on without the compendiums, this re-issue is an essential purchase which offers both core reference material and an inspirational glimpse of the Demiplane's dark heart."[6]
David Comford reviewed Monstrous Compendium Annual Volume Three for Arcane magazine, rating it a 4 out of 10 overall.[5] He commented that "The strength of the annual is that the contents are drawn from a variety of AD&D settings. Creatures from the TSR magazines, Forgotten Realms, Birthright, Ravenloft, Dark Sun, Al-Quadim and Greyhawk can be found giving referees access to monsters with abilities that otherwise might not have been thought of."[5] However, he questioned, "Are a few interesting ideas and cross-over scenarios worth over a tenner, though? Well, TSR has released such a stupefying amount of products to date that every referee should have a decent supply of challenging monsters available for them to use. If you don't, then have a flick through this for a few new ideas, but think twice before you buy it."[5] Comford concluded his review by saying, "Volume three is a mixed bunch. Bar a few good entries it falls into a compilation of variations on a theme which, with a little time and imagination, most referees could come up with."[5]
