I've just been reminded that there are two editions of Human Occupied Landfill (HōL) – the first one published in 1994, the second one in 2002. I own the first edition core rulebook, as well as its sole (?) supplement, Buttery Wholesomeness.
Are there any significant differences between the two editions of HōL?
Also, am I right about the number and publication dates of the editions? (I did google them, but I'm not entirely sure about the reliability of the sources I've found.)
