In theory or in practice? IME the details of what could be done in a melee round, and how far you could move, etc. required a lot of subjective DM judgement. This, and the fact that melee rounds were 1 minute long meant that 1E was not nearly as min-dependant and tactical as 3E is. IME the fact that DnD was supposedly derived from Chainmail didn't mean what you would think - I don't think I ever played ADnD with anyone who had ever played Chainmail.
Steely Dan said:Look, D&D has always been two games, amateur dramatics/storytelling (non-combat), and a board game (combat) – get over it.
"Get over it" is always unreliable advice IMO. DnD has not always been balanced between dramatic and board-game elements in the same proportions through all editions. Sometimes the proportions were encouraged by the rules, but probably more often it was just a matter of the current gamer culture.
