Seeing as we are resurrecting topics from the long dead, I suppose I could share something in this vein as it is still interesting, even years later. That said, the first of which I have to share is that I am woefully self-conscious about writing human characters. How does one write for people? For the life of me, even if others claim it is fine or better yet well-written and credible, I dread writing anything outside of those animal, namely those things people. At least with some fantasy races or fictional species such as with those things extraterrestrial I can tap into their undertones and make them closer to overt, to make them different and distinct, but people? Writing people is a terrible experience for me because I haven't the faintest how they should behave as people. As characters, certainly, that is no challenge - what motivates them, what they think, why they think it - but how to encapsulate that as a human being? A different challenge altogether.
The second that I will share for the time being is that I absolutely despise not being able to continue characters. The idea of writing expendable, or that which I perceive as such, characters who cannot progress from topic to topic with time is just a baffling and frustrating thing. I came up in a time where it was unusual to have more than one character and all the investment, everything itself, went into that one character, who moved and progressed through various narratives and places. Yet now it feels as though the written roleplaying world is made up of but islands, all separate, and to the extent that one cannot even navigate to most of them from another. Thus one needs make a character for each and that certainly does rub the fur the wrong way.
