But with Greyhawk and/or Blackmoor you have already created a second instance. You are no longer using the prior singularity of D&D. You have changed it so of course the feel would be different.
Chainmail -1971
D&D -1974
Greyhawk SUPPLEMENT I, Blackmoor SUPPLEMENT II -1975
D&D was a 3 book set, that got followed after that with the same structure. But that game was not the same game when you added stuff to it.
Like any "splat"book or accessory or supplemental material will change the game and how it feels. Thus after adding anything new, even Greyhawk or Blackmoor, you have already split off from the initial "D&D Experience".
This isn't about splat material. Those campaigns were running before the first ruleset was even published. The initial D&D experience happened before the rules saw publication. Sorry you missed the boat. I guess you will have to settle for just the 1974 OD&D rules. Of course by the time of the printing, some changes were made and the essence of true game was lost. What a shame.
