Which books to get? To play in games run by someone else you just need the Player's Book, which contains the complete game rules plus all character options. To run your own games you also need the Referee's Book, which contains a massive bestiary, hoard of magic items, and advice on running games.

Older core books: Prior to 2026, Old-School Essentials was published in several forms, some of which are still available. See About Old-School Essentials for a full run-down on older versions.
