My question to those that want to play something truly "exotic" is how do you do it?
I mean, playing a Lizard would be so foreign to a human thought process that I do not know how one would do it - after all you have spent X number of years having your brain wired to think like a human and suddenly you are a Sahougin for a couple of hours a week - I just don't see it being done (or at least with any sort of justice)
In my mind, that is why the Demi-Humans work, because while not strickly human, they are human enought that we can "act" the part with little to no difficulty.
