After months of dibbling and dabbling, I have a working copy of my Goblin Laws of Gaming/Into the Odd RPG hack: CATACOMBERS. Get the PDF here.
This game is designed to be played in a medieval-esque fantasy world, where human beings are the norm and other races & monsters are strange and mysterious. You could probably jam in whatever gonzo weirdness you like along the way, but player characters start off fairly 'normal.' It has a lot of generally-accepted OSR contents, like XP-for-gold, exploration turns, and encounter dice. It also has lots of GLOG-type stuff, including the magic and class templates. The combat is taken wholesale from Into the Odd with just some minor adjustments.
I now will go through the whole document, section by section, just rambling about why I made certain decision.
