Osric Unearthed

There are a lot of RPG and ORPG products out there, one of them is a 42 page PDF written by Charles Rice Osric Unearthed

James from Grognardia reviewed it in depth, and one of the most interesting things he says is this

Obviously, it’s intended for use with OSRIC, but some of its contents could be fairly easily adapted to other old school fantasy RPGs — some but not all. I say that because a goodly portion of OSRIC Unearthed is devoted to “martial arts” (a broad term encompassing a variety of combat styles and maneuvers, not just Asian-derived unarmed combat) and uses OSRIC’s weapon proficiency rules as their basis. Games like Labyrinth Lord and Swords & Wizardry both lack such rules, making it harder to introduce these martial arts into those games without also importing weapon proficiencies or something akin to them. It’s not an insurmountable difficulty by any means, but I felt I should mention that, unlike many old school products, OSRIC Unearthed is fairly strongly mechanically connected to its native rules set.

He has a lot more to say about it, so before you run out to buy it yourselves, stop by  and read his review
