i really like this idea! a cool path would be a hyper fetish path or a video game nerd path? (as a way for the dev to add his own game taste of video games from 10+ years ago)
Or maybe a scary dom path, like making her into a scary analog horror monster (with big ol knockers) but she is still a super sweet person. :D
Or better yet is to have some paths extend, but branch out to various ways based on the location. Such as the PET path progressing further in the park, with the choice of progressing as a wild wolf-hybrid or as a domestic dog-hybrid. The same could be for HYPNOSIS path, being able to choose between like you said with videogame nerd or dominate business boss. I also can see for a MUSCLE GROWTH path taking place at the GYM, but what would be a nice twist would be to have a WEIGHT GAIN GROWTH path there as well. But again, this is just me typing ideas. I just hope this continues to progress and become a masterpiece of its own someday.
