The story itself is meant as entertainment, not "art", and keeping that in mind has made it a lot easier to write. In fact, aside from the (negligible) literary value of the story itself, the project has gotten me in the habit of writing, which is something that hadn't happened before. What I'm saying is, it was a great way to get past perfectionism and other self-defeating habits, and build momentum, confidence, and proficiency. So if I do get ambitious in the future and aspire to writing something a little more serious, I'll be in a much better position to do it.
Meanwhile ... just in case you're wondering what language the characters are speaking, I've created a Gilkesh language home page. Currently posted are PDFs of the 600-word core vocabulary; in the future I'll add sections on the grammar.
So if you were looking for conclusive proof that I have way too much time on my hands, there you are.
