In this interview, he almost doesn't finish saying it but he admits to being or at some point having been an avid DnD player!

Wait, SL, we knew this.

I mean, for fucks sake, he wrote the intro to the D&D 20th anniversary book.

Though it may not have been the into, but I know he did write something for it.

And that was like, what? 5 years ago? More?

...well I didn't know? Really? He actually wrote for DnD That's kinda cool...

Its never been my fav game/system though...Ive spent the last 5 years playing Aberrant!

I know he is/was a gamer. Which means... he still qualifies to date me. Vin! Baby! Don't be a stranger!

Riddick is apparently based on a character he ran (how he plays Riddick at least, he didn't write the movie or anything)

That makes me laugh, because I based a character off of Riddick (loosely, of course). It's actually seen limited play here, on this board.

Anyone who watched Chronicles of Riddick and did not immediately realise it was Vin Diesel showing off how awesome his favourite RPG character is was clearly not paying attention. It is nearly a textbook Character spiel from any one of my friends, or even myself...
