I'm around 75 pages so far and I plan to make it between 250-300 pages, but I might make it just above 200 depending on how the story progresses and what I can think of to add that I like. Its still fairly early in the story.
It helps to bare in mind that humans have gotten to a point to where we can make a living off of this sort of stuff. Years ago, if you didn't hunt, you didn't eat. Now we can do what we like to make money and survive.
Well, that's not ALWAYS true, and hunting hasn't really been necessary for a couple centuries, but yeah, it's cool that creativity and freedom of expression can drive a career now. I love it.
