Picked up the bundle a week ago. Flipped through the "501 Plots" book and copied a half dozen into my random encounter lists for my Aftermath! RPG. I did the same for my random NPC lists for the same game, from the "1.000 NPC;s" book. During the game, a random roll opened one of the plots and a pair of the NPC's. (Evil villains) Easiest random encounter set up I've ever done. The plot and one of the NPC;s have been integrated into the game as part of the long term story arc and the gamers have discovered a truly psychopathic villain who wants their heads on a spike in revenge! Totally delightful! Highly recommend it. Great value, if only to read and 'cherry pick' ideas.

Both of these products have helped me either come up with adventures or fleshed out adventures. Very good products for any GM who wants a continue to add flavor and depth to their campaigns.

I don't think it is worth the pain of writing a full-blown review for Eureka and Masks. Trolling the net you will stumble upon tons of enthusiastic opinions about both products. Here is mine! I'll cut is short. If you fall in one of following descriptions:

• game master (or GM wannabe)
• designer/author
• writer
• illustrator/visual artist (yep, I'm serious) then, simply put, buy this bundle. Maybe you still don't know but you need both the books. Dot.

If you don't, keep away! Reading such material could spoil years of gameplay, even if your master doesn't use it. Believe me! These are that kind of books that should be kept right behind GM screen (or in a writer secret drawer) to express their full potential.

With Crimson Exodus, this is the best product I've ever bought on this site.
