I found out about GORE from talk over at the Mongoose Runequest forums, where quite a bit of discussion has come out of this product. After finding out it was available as an at-cost print copy I grabbed one. GORE is basically an OGL/SRD edition of the basic role playing system, or a variant there with, which was pioneered by Chaosium games back in the 70's, first with Runequest and then Call of Cthulhu. This version uses the current SRD material for Runequest to reconstruct more traditional elements of the BRP system while integrating features of the new RQ variant. Opposition rolls (read: resistance table) are in this edition, for example, something more familiar to CoC players than MRQers.
The book gives you the whole essential system for running anything under the sun, minus all the genre-specific details, although a basic OGL-inspired magic system is included. Any entrepeneurial GM could easily use this as the basis for a campaign, and enough equipment is thrown in to provide for fantasy or modern gaming. No monsters are included, although the Mongoose SRD would have plenty of that (or buy Mongoose's Monsters book for MRQ).
In the end, this book is essentially compatible with all BRP products to date, with minimal fuss for the most part. It is really intended for other publishers who like using the SRD/OGL format to write BRP-compatible material, or more accurately GORE compatible material that just happens to be BRP compatible, as well. The web site for the publisher is set up with the details on how to do this, and I am tempted to use GORE as the basis for some of my own publishing ventures. Anyway, this is a good, solid product for those who have A: nostalgic fondness for the BRP system from yore, B: a desire to publish material in SRD/OGL format using said system, and C: might like BRP ut are not 100% happy with the specific format/rules of the Mongoose Runequest edition. I'm crossing my fingers and hope GORE serves us all well until Chaosium eventually releases the deluxe Basic Roleplaying set.
