I ran A Sundered World a few days ago using FrankenFourth. Adam wanted to keep playing Waive from our previous Dungeon World campaigns, so he rolled up a scion (ie, human) nomad, Shane went with a tarchon battlemind (surprising no one), and Melissa ended up with an ishim blasty wizard.
I'll do a playtest report soon (probably tomorrow), I'm only mentioning it because they just started their foray into a Gigeresque snail dungeon. By the time we got the characters and gear settled there was only about a half-hour left; thus far they've only encountered a quartet of giant snails (which means they're human-sized) crawling about a field of jagged, tooth-like growths.
Hopefully next time they'll run into the weirder shit I've cooked up. Not only the snail stuff I've already posted, but, say, a snail with a rocket pack bolted to its shell because snails are slow and why the hell didn't I put this in A Sundered World: Player Fragments?
A Sundered World: Player Fragments, the first supplement for A Sundered World, is finally out!
If you're looking for a class that lets you play almost any were-thing you want (plus a bunch of related extra content), then check out The Therianthrope. There's also The Dragon, a class that lets you play almost any dragon-ish thing you could think of.
By fan demand, we've mashed all of our 10+ Treasure volumes into one big magic item book, making it cheaper and more convenient to buy in print (which you can now do).
