OD&D or Dungeons & Dragons Original Edition or D&D 0e is where tabletop role-playing games began. Dungeons and Dragons grew out of war gaming but quickly became its own category of gaming.
If you want to go back to the beginning to see where tabletop RPGs began or you want to relive the glory day when you discovered D&D, now you are in luck.
Wizards of the Coast has released many of the OD&D PDFs. The PDFs are very reasonably priced and showcase the rules that launched thousands of RPG campaigns.
