>>44588321The human cast has potential, but you never really get a deeper glimpse of what their lives are or who they are, just the surface level ideas.
Ironically the games that handled the cast's characterization the best (by no means is it "great" outside of Pokemon standards though, HGSS with its phone calls and gym leaders doing things outside at certain times) was seen as inconvenient as you have to find obtuse ways to interact with the latter, and the former tended to interrupt the flow of gameplay with constant calls.
