So I really need to look at how to push this forward -- and to exploit the related talents I have of visualization and game design.
Near as I can tell, this means I need to do three things:
1) Develop a backlog of material, so if I get people interested in my stuff, I have something on hand.
2) Get an agent. Possibly two, since most book agents don't do movie, etc., agenting, and in general no one in the movie, TV, or video game industries will talk to you without either an agent or an "in" from Someone Who Knows Someone.
3) (speculative) Find a partner or partners who can help me develop at least one story or concept into demo media -- or, if the technology's gone far enough, a full-blown movie. I can script, I could probably direct to some extent, I can do some acting (especially voices for an animated or CGI character).
The latter point is one I've been thinking about for quite a while. Modern technology has been advancing in leaps and bounds. A lot of my material is very visually oriented. I "see" the movies in my mind. I can write the scripts without almost any effort -- I can see the shots, the zoom in and out, panning, movement...
...but I can't even do a still image worth looking at.
Nor can I code an RPG myself.
But if the technology has advanced far enough that I can do either one for a reasonable price, this is a potential way for me to advance my career that is not yet terribly common.
I'm posting this mainly to reinforce my resolve to start moving forward on at least the first two, and keep an eye out for opportunities to possibly advance the third.
