Penny Arcade is actually attempting (kind of) to get him to join them in one of their podcasted D&D campaigns (despite the very real possibility that putting both Riddick and Wesley Crusher in the same room would destroy the universe). It gets better: one of the upcoming games is about his player character. When they released the sequel, a large percentage of its sales were just because it included the original levels. Their first project (although not for long) was teaming up with Starbreeze Studios to make The Chronicles of Riddick: Escape from Butcher Bay, which many people named as actually being better than the accompanying film, and was named as being the best action game on the Xbox at the time.
Seriously, the guy loves Dungeons & Dragons so much, he wrote his own campaigns, got a temp tattoo of the name of his D&D character in XXX (it's " Melkor", if you're wondering), and even started his own video game company because he was tired of people making crappy video games out of his movies. A massive geek who could break your spine. However, unlike most action stars, Vin has a huge advantage that helps to get him fanboys: he is a massive geek. Vin has spent most of his film career playing bald, brawny badass guys who sound like they use mint-flavoured gravel and whiskey for mouthwash (which is the basis of his appeal for some). He is the Scary Black Man, only (mostly) white. Mark Sinclair (born July 18, 1967), better known as Vin Diesel, is an American actor, producer, director and screenwriter.
