We definitely understand concerns about stagnation for players who've gotten into the postgame period. However, our aim is to create an environment where players can pursue whatever character goals they choose, regardless of how long they've been in the game. In addition to breeding and various slice of life activities (which could consist of anything from opening a business to sightseeing to challenging the Gym Leader Elite Teams and so on), there's also plenty of room for player run events to change things up a little, and we definitely encourage characters to run them! So if there's something you'd like to do, feel free to contact us about doing it, or if it's something your characters wouldn't go for, you can always pitch it as a regular plot via our Plot Suggestions post.
