Bottom Line: Does it do what it says (give tables that generate interesting natural-not-dungeon caves?) Yes. Was it worth $5? It was to me.

The rest are just nits for the prehistoric purist such as myself.

As most of these products do, there is a subtle D&D bias that assumes these are going to be placed in a bog-standard 'Elf/Dwarf/Hobbit' fantasy world. Doesn’t detract from the product much but it shows its head when "Strange/Rare" results are generated, instead of supplying a table it just says "go look in your D&D books!". I'm paraphrasing. Sigh.

Very good spelling and grammar. Always a surprise in these products.

The tables will not produce a map. Sizes are given as Small, Medium, Large and Huge. It don’t consider this a fatal flaw, but some will and it does seem like it would have been pretty easy to add one page to fix this. Small = 10’x10’, Large = 20’x20’, etc.

My biggest gripe is that the maps appear to be able to appear in ANY terrain. The terrain where the cave is found is never addressed at all. Even Judges Guild back in its Caves & Caverns book did that.

So for example, a Limestone cave could appear anywhere and a “Marl” can has the same chance of appearing as a “Variolite” cave. A Basalt cave (volcanic) could appear deep in the heart of a jungle.

I don’t know geography well enough to know if this is true or not. I was hoping that this type of research was part of what I’m paying for.

Metal/Gem deposits are very good and well thought out. No mention of the quantity or location however.

I appreciated the brief but complete descriptions. Enough to use in play but not so much it looked like a wiki entry was copy-and-pasted.

Cave smells is very cool.

Seems like it would be more convenient to have Cave Entrances in the front of the book. No big deal.

I’m a little disappointed that the Cave Entrances have so much man-made technology in them. For prehistoric role-playing I’ll have to make my own table to get rid of those entries. No big deal.

Hallway and Room features are very nice, though the tables seem to generate a LOT of ‘dead end’ Hallways.

Overall, I nicely done supplement, well priced for what it is and complete enough so that no two caves will ever be exactly the same.

That’s what I was looking for and that’s what I got.

Thanks! I’m definitely going to TableSmith this for my OG games!
