Having played week 4, I have to say, I'm really looking forward to the finished game!
I've no complaints, but more of a query:
Having created two goths - one top-heavy, the other bottom-heavy -, there's reason to assume that the third one would be a belly-heavy or fat goth (then again, there's the former necromancer who more or less fits that role, but she isn't explicitly a goth).
Considering the aforementioned Big Titty Goth and Big Booty Goths were a warrior and a rogue, all signs point towards the Big Belly Goth being a mage - and there's plenty of those to pick from.
My personal vote is on Karen - it would be hilarious to see her become one by some quirk of the Gothinomicon and other circumstances.
