The "Old School Reference and Index Compilation™", or "OSRIC™", is the retro-clone of the Advanced Dungeons & Dragons™ First Edition game published by TSR, Inc. in the late 1970's and early 1980's. First released in 2006, OSRIC was one of the first retro-clones to hit the gaming scene and garnered a great deal of attention, both good and ill, from the larger gaming community. OSRIC paved the way for other retro-clones such as Labyrinth Lord™ (retro-clone of the Moldvay Basic/Expert D&D™ game) and Swords & Wizardry™ (retro-clone of the Original Dungeons & Dragons™ game, or OD&D™ ).
