Well, my wife and I will both be playing, and I plan for my kids to play when they're old enough, so it's our family name in the credits. Still not sure if I want to put clan or family after it, though.
I'd wondered about the idea of using the nickname-in-quotes means as I'd also like my real name but it'd be nice to be identified by my forum name too. It seems that the general consensus so far is to use real names, which is probably the sensible approach! Even though being sensible is a concept I often struggle with.
In one of the kickstarter videos a sheep was attacked (with a fireball IIRC), and since the death animations were not done at the time, it kind of looked like it just exploded. In the kickstarter comments discussing additions or stretch goals, someone suggested sheep armour, after which someone posted a link to a screenshot from a low budget horror comedy called Black Sheep, which got a bunch of similar images linked to (most from that film, weresheep not being a large sub-genre), and weresheep became a running theme.
