Hi Tal, I am not particularly good at writing reviews but I have purchased both these books and found them to have been a worthwhile investment.
Dream Realms is not the thickest of books for the money but it has lots of good stuff inside.
The first chapter is "Adventures in Dreams".(7 pages)
It contains a new sorcerous skill called Dreamcrafting. This is the chaotic counterpart to the Lawful Dreamthieves. There is crunch and an opposed table for the manipulation of dreams and some good stuff on how things work in the dream realms.
The second chapter is "The Seven Dream Realms"(16 Pages)
This contains a lot of stuff that has been printed before. I imagine that it is only reprinted for the sake of completeness. I haven't really had time to totally go through this chapter for a number of reasons but at least some of it appears to be a cut and paste job.
The third chapter is "The Dream Market"(5 Pages)
All new stuff on finding the Dream Market and the price of dreams. Some interesting stuff on how to become a Dreamthief as well.
The fourth chapter is "The Thousand Year Dream"(15 pages)
Melniboneans and dream couches. Experiencing the dream fluff and crunch for the visited worlds including lotsa new critters and an advanced firearms table. Suggestions for how to use firearms in Eternal Champion games without them taking over.
New critters are-Kakatanawa, Pukawatchi, Cowardly Serpents, Kenabik, Uria Ne Barbarians, Mittelmarch Panther, Off Moo and Troogs.
The fifth chapter is "A Vengeance Long Dreamt Of"(25 pages)
A scenario-utilising many of the concepts previously discussed in the other chapters. Its good and i'm looking forward to running it with my group. Includes fully statted NPC's
The sixth chapter is "Dream Travellers and Other Personalities"(12 Pages)
Exactly what the name suggests. Character fully statted out and described are, Alnec Kreb, Ayanawatta, Chamog Borm, Gho Faazi, Jhary-A -Conel and Whiskers(reprint), Johannes Klosterheim 8) (my favourite-worth the price alone AFAIC), Manag Iss, Oona, Oone, Varadia and White Crow.
The seventh chapter is "Tanelorn"(12 pages)
Description of city with decent map(shocker). Notables and districts in detail as well as how to get there , in dreams or otherwise.
All in all I would give this a 4 out of 5 due to some previously available material in reprint.
Hope this helps.
