I'm a lifelong Conan fan and this bundle is amazing. This collection is best used purely for the setting. 2D20 has its critics and in my opinion, deservingly so, but they did a wonderful job at expanding Robert E. Howard's Hyborian Age. The Monolith Source Book is particularly wonderful and a complete must buy if you own the board game. The Solo/Co-op campaign for the board game in this book is one of the best Conan experiences in gaming I've had. The art in this collection is something else entirely to be marveled at. It will not only capture you with its beauty, but it is near magical how it can conjure wonderful ideas for your gaming needs. Even if 2D20 isn't your thing, this setting is so well done that these books and stories would be a wonderful addition to your idea pool for any of your RPG needs. I've personally used it for rules lite rpgs when running one shots. I've borrowed heavily from it for my DnD games. I've also enjoyed many a night playing it straight out of the source in the 2d20 world. This collection is a pricey investment, but worth every penny. Happy gaming Dog Brothers!
