I'm a sucker for the from the dawn of time concept. From Quest for Fire, to Early Man, this is a fun scenerio.
It gave me much pleasure when I heard about this product. The good folk at Fat Goblin Games have really outdone themselves by balencing a new concept while not overcomplicating things.
I serious enjoy the use of ape and dinosaur folk pcs to be added to any future games I play.
The revision of equipment is inspired. In particular, I am amused by the new trinkets.
For a project like this, a lot of interpretation is required and they do it well. I love their explanations of how to shoe horn in their ideas in other games and where they would fit as well as the pros and cons of each approach.
Now if you'll excuse me, I'm using this to create a game of Yor.
