This 7-page PDF confused me at first. Some months ago, I reviewed another PDF entitled Original Edition Characters, produced by Goblinoid Games in order tweak the rules of the excellent Labyrinth Lord to play a bit more like those from the little brown books of OD&D. Given that this product, published by Brave Halfling, uses very similar trade dress (intended to recall the White Box), I suppose the confusion was inevitable. In point of fact, though, the “Original Edition Options” line, of which Cavalier, Paladin & Squire is one example, isn’t a support product for Labyrinth Lord alone, but for all OD&D-descended retro-clones and simulacra, including Swords & Wizardry. Unsurprisingly, I think this is terrific and evidence of just how compatible the pre-WotC editions of Dungeons & Dragons were with one another, despite their having been packaged and marketed differently from another another.
