||First of all I need to tell that I bought this product mainly out of curiosity, as I don't play anymore AD&D 1e. However, I collect the material and did play for years.
EDIT: after re-reading the PDF more carefully, it appeared better to me. So, I think it's an excellent addition to the OSRIC game.
This OSRIC supplement is from Charles Rice, the author of the excellent d20 supplements "Legends of Excalibur" and "Legends of Samurai".
The main point is that it presents 9 new character classes: Barbarian, Bard, Brawler, Knight, Ninja, Noble, Samurai, Thief-acrobat, Yamabushi. They are vaguely inspired from UA and OA, but are balanced against the OSRIC base classes. Unfortunately, in some cases they appear a little lackluster compared to their predecessors. In any case, these nine classes should be an excellent addition to OSRIC. Then, the magical items and the martial-arts should greatly add to the game. All of this makes the supplement really worth it.
LIKED: Combat maneuvers and martial arts are the best part of this book. The classes should complete the core OSRIC classes fairly well.
DISLIKED: Some classes are a little lackluster.
QUALITY: Very Good
