6. Dungeons & Dragons Loves Him
TSR Inc. and Wizards of the Coast, creators and publishers of Dungeons and Dragons, asked Diesel to write the foreword for 30 Years of Adventure: A Celebration of Dungeons and Dragons, a book celebrating the 30th anniversary of Dungeons and Dragons.
He's quoted in the foreword as saying:
We were all drawn to the game because it allowed us to become these characters, vastly different in appearance and in action, but what kept us hooked was the search for the character that represented our higher self. Playing D&D was a training ground for our imaginations and an opportunity to explore our identities.
Looks like Vin Diesel can also add "philosopher" to his job titles.
Here's a screen cap of the back of the book featuring the quote.
