I like role-playing games that try new things, and when it's in the form itself that there is experimentation, I'm even more a customer. Mud is on the border of role-playing, as it seems to be more of a first-person interactive story, something close to a contemplative video game with several possible endings... But most of all, it's in the form of a comic book illustrated with wispy blobs and blurred outlines, making the story of this golem something touching outside of any game. I felt like I was playing Mud just by reading it, and it was quite an experience.
