This is obvious sophistry. First decade of D&D means first decade of D&D, it's not rocket science.

You don't start in 1972 because D&D was published in 1974.

You don't start in 1979 because D&D was published in 1974.

>B-but what if the decade starts in 2007?
Then it's not the first decade of D&D.
