I prefer to think of it from the perspective that we've done such a good job with our newer characters that people are clamoring for more. Admittedly, the four main routes were decided before most of these characters even existed, and we'd love to explore those characters a little deeper too. Ultimately that's what the Tales mode will facilitate and as of right now, we plan to continue adding content after 1.0 while there's demand for it. So long as enough people are supporting us over on Patreon, we'll continue to add the things people want to see!
