This just happened today, and it wasn’t the first time… our group is playing a D&D campaign, but heavy in RP. The DM has been skipping out on supposedly scheduled meetings, and treats the majority of the group like crap a lot of time. When confronted, he refuses to admit that he’s doing something wrong, and threatens to let the group just drop altogether.
One of the benefits of collaborative storytelling or RP on twitter, tumblr, Wordpress, proboards or similar places is they don’t have dungeon/game masters. It’s also one of the disadvantages….
