I thought I should drop a note to say that our current Unstable release now supports Wolfenstein 3D, Spear of Destiny, and Super Noah's Ark 3D (although this one is a little more basic). I've also started to actually fold in previous Oblige versions themselves into the codebase, starting with v0.94. I'm hoping that eventually the program becomes a sort of anthology of all of the things that Oblige supported over the years.
Wow dude, just yesterday I was thinking about making adding Hexen actions for monsters to my mbf2.04 fork for one of my wads.
And today I see something related to my thoughts. Gonna check it out when I have time
