The card mechanic can be a little confusing at first, but the duels are fun and I like it. It gives you a taste of the game and leaves you wanting to go buy the full book. So as a preview it is spot on and I recommend people try it out.
The temple of Issoth delivers a fun Solitare adventure for Warriors. It comes with 3 pregenerated characters if you do not have time to make one of your own. I have actually strung this adventure and some other solos into a saga for my warrior characters.
I bought Beast and Barbarians Gold Edition as part of the GRAmel starter set. I am so glad I did!! It captures the Sword and Sorcery Genre perfectly. It explains the genre so even a complete novice can get it but does not feel cumbersome or overwhelming. There is no dead weight or filler in this book but it isn't pure crunch either. If you have any interest if capturing the feel of Conan or other sword and sorcery settings in your game I strongly advise you get this book.
