I've previously owned the OSRIC hardcover, but I just recently invested in the A5 (8.3 x 5.8 inch) "mini" edition and I can't really remember another case where a game book's form has so improved its function. Fact is, the hardcover is right about the size and weight of an AD&D PHB and MM combined. The miniature edition is half that size and even less than half that weight. Being able to hold all this gaing goodness in the palm of my hand is heady. And the text is still easy to make out, unlike in those novelty 2 x 3 inch AD&D collectibles that came out around 1999. Plus, reading something the dimensions and heft of a paperback novel on the bus is much easier than lugging around a full-size "gaming textbook." I wish more RPG sellers would offer options like this. This new presentation alone has sold me on actually using OSRIC for gaming purposes as opposed to just owning it as a curiousity. Are you listening, Proctor and Finch?
