This group holds all of the d20 System Products that are compatible with D&D 3.0 and any other d20 RPG of that era. There are other groups for 3.5 and 4th edition d20 System products. Products not bearing the official logo of Dungeons & Dragons from WotC should go in one of these "d20 System Products" groups rather than the official D&D groups.
