SJG launched this Kickstarter:
The only game - or supplement - I don't have but want is Necromancer. I'm not sure I want it for $20+shipping. I have the rest of the ones already - Ogre, GEV, even Boat Wars. I don't have Undead but I have the very similar Vampire by TSR.
Still, if you pine for any of those, it looks like it will fund.
