Backed seventeen:
Order of the Stick, Rebuilding ENWorld, Eclipse Phase: Transhuman, both Pathfinder Online KS, Prismatic Art collection, Hex, a Shadows of Esteren, Relaunch Know Direction, Reaper 1-3, Advanced Bestiary, Reading Rainbow, Karthun, Ghostbusters, and now Tome of Beasts.
Tome of Beasts just finished. Karthun is also ongoing and rather late (delivery estimated in September) but small publisher. Ghostbusters is shipping so any day now. And Reaper doesn't owe me anything until next September.
My Know Direction reward is a little late. But I haven't pressed as I had an exclusive thing, and there's generic rewards still ongoing. And Order of the Stick got 80% of what I paid for out, and just waiting on a few PDFs.
My success rate is pretty high. 100% for funding and pretty high for getting what I paid for.
