"I'm looking at Dungeon Raiders and I REALLY LIKE IT." -- @koboldstyle, creator of Old School Hack
Yet another retroclone, Dungeon Raiders simplifies Original D&D and early D&D into one straightforward fantasy RPG system. Included are stats, rules, and spells for characters up to level 3, and it'll probably take you a while to get there, thanks to the lists of monsters and treasure for your party to encounter.
This download includes the PDF, MOBI (Kindle eReaders), and EPUB (Nook and Kobo eReaders) versions.
