Hey, watch them if you'd like they're not all that bad and a couple are kind of insightful. Keep in mind they're kind of old, I think Frag is the newest one, but I will admitly say that Second Skin is quite possibly my favorite... Being a Warhammer: Age of Reckoning Vet, you can imagine why (Hint/Spoiler The Asian that may have ruined it all). Anyways, here are some links.
Frag the Movie
Concerns the different groupings and demographics of gamers from the beginning to present day. Casual to Professional, it has a bit more serious tone, but if you enjoy gaming at all, it's definitely worth a watch.
This is more aimed at the MMO genre and in particular WoW/EverQuest II. It targets the more "addicted" side of Gamers. You may even see a few familiar faces in this flick!
