(When I began this effort, I was just enjoying feeling productive again and didn't have any real plan to release. But I've been pleased enough with how it's been coming along that I've started seriously thinking about it.)
Fortunately, I personally enjoy writing. Currently, I wouldn't be able to claim that Claude didn't contribute to the writing, but nothing in Vestiges should sound like genAI. (Which is actually a little funny to me since one of the characters is an AI. But the genAI writing style grates on many, including myself, and I'd imagine that 20+ years into the future, such issues will have been solved.)
(I've considered trying to find an artist to work with to have professional 2D art.)
