Round Robin stories are a mixed bag, but I had a lot of fun listening to this one.
I particularly adored Robert E. Howard's playfulness. Lovecraft is being as stereotypically lovecraftian as possible and then Howard comes in and goes, "Nah, scratch that, this is now sword-and-sorcery in space." I was not expecting to laugh that hard during my commute today.
I'll have to look into Frank Belknap Long. I haven't read any of his work before, but I'm definitely intrigued now.
