A while back, I got linked to DM of the rings (http://www.shamusyoung.com/twentysidedtale/?cat=14), a webcomic about an unstoppably railroaded D&D campaign through middle earth. It was hilarious stuff, but once it ended, I was looking for something else in the same vein. Thus came Darths and Droids (http://www.irregularwebcomic.net/darthsanddroids/episodes/0001.html) which follows the same basic idea of it being a campaign through a well known movie, with the main difference being the DM for Darths and Droids is much more flexible than the DM of the Rings. DMotR is a railroad, while D&D is a runaway campaign.
Give them both a try.
I was never much an RPG'er - but the D&D strip was a riot.
Thanks for the link!!!
