So I'd like to ask writers that are strong in these areas for advice, especially when it comes to writing in games. In particular, on delivering moral messages as well as social, political and legal commentary with the right level of subtlety and making complex philosophical points comprehensible to those who are not as erudite as I am.
This is closely related to something I learned from my own progress as a writer and from film school, where you just write the story, and themes, morals, and questions will automatically begin to emerge from it as you review it and think it over. I never write anything with a specific message in mind. I only write a story that happens to have an underlying point or theme to it.
I didn't go into writing the script for the surreal fantasy adventure game I'm working on thinking: "OK, it's going to be about the balance and interplay of power, freedom and responsibility; about growing up, coming of age, and finding your place and purpose in the world." Of course not. I just wrote what I thought would be a good story, and I only realized afterward that those where the things it was about, under the surface. Same with the script for a 45-minute animated film I wrote an number of years ago, now. I didn't realize until after I'd written it that it was really about coping with grief and loss; moving on with your life, and continuing to live life fully, despite whatever reality throws at you. Again with the post-cyberpunk novel I'm writing, as well- but you get the idea.
