To get the 'feel' of the Shifters universe, I highly suggest you go and rent yourself the following videos to get the 'feel' behind what Shifters is like. A lot of people walk into the RP thinking that its just a contemporary environment or its 'whitewolf' of another flavor. Newsflash, its not.
When you are creating a character, you have to keep in mind the sort of world they are living in and the sort of people they will be as a result. Also, studying the main characters from other media of similar type can help you to develop interesting characters of your own.
