I am looking over the material and find myself thinking that Caverns of Thracia is like one part Island o Dread (as a Hexcrawl players fill in the missing hex information to discover), one part Keep on the Borderlands where you face off against numerous organized (in some fashion) Humanoids, but instead of Caves of Chaos it is Caverns of Thracia, one part Lost City B4 and instead of the evil 'god' thing of that module you have gods like Thanos and his cult, plus we could probably add that module of the other Lost City with the bullyfrog people on it, as this is also an above ground abandoned evil city. Put another way, it is 'like' parts of the concepts that lay at the foundation for these many other games, but rolled into a single module. All drenched in a heavy Mythic Earth theme so I found myself thinking 'You know Aeon Ancient Greece DCC rules would be fantastic with this'. You can make the humans more modern versions of Thracians or other similar 'Greek' humans who come to the once thriving frontier called Thracia, a now fallen kingdom, sort of like classical era Greeks going back to a place that once existed in the earlier Bronze Hellenistic age or perhaps fell in the Greek Dark ages, or even after this as Classic Greece doesn't occur till centuries later. Of course this is just one possibility and a way to use the rules from that DCC third party rules set, or a more modern traditional group of DCC player characters could be used ---- SPOILER ALERT. Do not read this if you don't want to know more about things in the module material. There were some odd choices in the module, like the MInotaur King has a Bull Rush style attack the text says he leads with in combat. I am thinking if he is so intelligent why would he ever do that. Sure if he is in tight close quarter combat that might make sense for the opening first round of combat, as the end result is to move someone back 20', but he has spells like Fireball and if he is not in close melee combat and sees the group all near one area. The first attack is not going to be some signature Bull Rush. that is not playing the Minotaur King smartly. So there are things like that in the book I thought 'Um, ok' and would ignore in real game play. I am also struck with how some of the potentially 'good' or netural monsters could become allies of the PC's but the book doesn't specifically suggest ways how that might be. Most likely it won't happen, but it is possible. Plus I could see things like the Stone Golem (with a Lions Head) which is a Guardian status, but why not have some way the players could gain control of it and use it as an ally. They also say the Minotaur King can summon the Water Elemental. But then say that it takes Read Magic to do that, and he can cast spells like a Wizard, but doesn't have Read Magic. I want to be that human slave who says 'Um your Lordly Kingship do you not have the proper magic to do this'. Apparently not, so the GM will have to give the Minotaur King access to Read Magic if the GM wants the Minotaur to do what the text suggests the Minotaur King could or might do with the water elemental which requires him to summon it. Those little oddities that stick out to me. The game also presents mercentary lizard men. Maybe the player characters can buy their service with lots of money as it does state they won't risk their life without the proper compensation. What if you provide that the player characters might have, at least for a time, one or more Lizard Men mercenaries in their service. I think this module has a few instances like that where allies can be gained, but the material does not really explore this other than presenting something, and letting the GM make connections, but in many cases they are rather obvious and yet the material suggests a possibly Dark Tower connection by switching out a monster. The material should have a little section on 'How to make Potential Allies' and the GM could modify things accordingly, such as allow the pc's a means to activate and control the guardian statue or not, but the option should exist potentially, rather than only be an obstacle. Also for the giant Snapping Turtle it is wasted saying it will simply latch on to (biting) some unlucky PC and the other characters potentially wack it to death though it has a nice AC. I saw a video of a real snapping turtle and they are llighting fast like many animals and swallow their prey whole. If you take a gaint sized version of something like the snapping turtle and it snaps at a human, it should be sufficiently Giant enough to swallow the human instantly. OR at the very least snap off a Limb, like a Leg or Foot and have rules for the chances of that. I would say this thing automatically causes a Critical Hit, and then why not create a little critical table for it, or use Monster Critical but since a critical should bite off, Snap Off that is, part of a target or swallow it whole, depending just how large the target is but if the turtle is large enough it should be able to do this. That would make this thing a lot scarier and deadly potentially. Now, you can save the swallowed PC'. It has hit points and a high AC, but now it can potentially swallow another PC. Maybe its limit is two or three Pcs. I cam thinking of the movie Blazing Saddles when the Sherriff says "Oh 15 sausages is my limit'. There might be a limit as the Turtle is an animal and can only eat so much, but it should be able to eat at least wo player characters. That would scare players. Go watch the real video of a snapping turtle eating. Go do that, and the go back and tell us how a giant version can't do that. Again, if not the whole creature, at least a limb. So not the whole player characters body, but if it is an Auto crit sort of like a Backstab attack and the result is a Severed Limb. Go look up the prehistoric fish that's mouth literally chops things in half super-lightning fast and the snapping turtle does something similar with a big shark pointy mouth. There should be at least a chance, a good one and the damage, depending on what is listed, for this initial snap attack should be more, like double something else, as it is a critical so some type of bonus damage. If it does less after that fine, I wish the rules had addressed something like this.
