Been looking through the rules of older editions, for reasons, and stumbled across this interesting section in the 1977 Holmes Basic Set:
1) There was originally going to be a witch class in AD&D? Wonder what that would have been like, especially in 1978? I imagine rather different than the warlock we know today...
2) The monk was originally going to be a variant cleric. (IIRC they did try to revive the monk in 2E as a cleric subtype.)
3) Half-elves are mentioned, but not half-orcs or gnomes (gnomes are listed later on, but only as a monster).
4) The only AD&D class option mentioned for dwarves, elves, and halflings is thief. However, maybe they figured dwarves' access to the fighter ("fighting man") class, elves' access to fighter and magic-user, and halflings' access to fighter in AD&D was already implied by them sharing the progression of those classes?
Thought this was also interesting:
Now, they don't tell you how to do this. But imagine if they had, and that sort of customization had been strongly supported from the game's early days?
