I used to play Dungeons and Dragons in high school with some exquisitely nerdy friends, and have collected a group of friends in grad school that are really excited to play. I'm really excited, because I'm approaching this as like a collaborative writing project. I've created an interesting world, and my friends are currently creating their characters. I'm approaching this experience much like I would an epic fantasy, with a lot of world building and direction and story-building. The really fun part is that I don't know how the stories are going to play out because I don't have any control over my characters. The collaboration is exciting. I've never done the RPG's on this site or elsewhere, but if any of you have and have any advice on how to make it a successful and rewarding experience, please help. Also, if you have any dungeon mastering experience, obviously I would like to hear about that, too.
