I just posted a Lord of the Rings related video over in the Non-Music Videos thread, and that reminded me of one of my favorite web comics,
The DM of the Rings. Basically, it's a humorous spin, using screencaps from the movies, on the fact that fantasy roleplaying games all have their roots in LotR, but LotR itself would make for a horrible RPG campaign.
Rather than make this a thread all about one particular comic, I thought I'd leave it open...what web comics, if any, do you read? I have around thirty in my RSS reader, and a handful of others that need to get RSS feeds so I don't need to remember to check them periodically.
