I know nothing of this quote, but my source was an interview or article from Gygax (pretty sure it was in The Dragon, but could be incorrect). Either Gygax fudged the truth to avoid embarrassment or Mondard did.No.
"Because in CHAINMAIL different weapons have different numbers to kill.
And I thought it would be cool if different weapons in D&D had different effects.
Gary didn't like the idea, but I didn't give up, and ultimately he did.
That's right, variable weapon damage is included in D&D because a 17 year old kid thought it was a neat idea and harassed the writer until he gave in.
I (expletive) you not.” -Mike Monard
That’s right. You can blame an obnoxious teenager. Gygax later went back to standardized weapon damage in a post-D&D system, IIRC.
