The common pirated version of Quake was a 20MB pre-release leak that had oodles and oodles of minor differences to the final version. All of the actual levels themselves are playable and completable. The funniest differences are a mean trap that was removed from the final E1M1, and E2M6 still begins with the eponymous oubliette, banished from official releases until 2021 (!).
