Yet another example of TSR following rather than leading.
I paid attention to the rule for just long enough to decide it was bunk, and have remained aware of it since as one of those dumb ideas in practice that somehow must have osunded good in theory...
impractical idea
Someone (and I'm not volunteering!) needs to run a D&D bootcamp, mandatory for all players who have only played 5e, where they spend six weekends playing old-school D&D in some form or other. Could be 0e, could be BX, could be 1e, whatever; the point being to expose them to the game's roots and make them aware of how it has since changed for both better and worse.
