Great Retroclone List

There’s a really comprehensive and informative list of all “retroclones” of D&D of just about every single edition. It contains things like OSR games (like Castles & Crusades and Labyrinth Lord) and newer homages (like Numenara and—my personal favorite—Dungeon World).

Really worth checking out:
