each character should to can sit down in the chairs in the pokemon center or other places that have chairs (excepting house), and the characters cannot to sit down in the hoenn pokemon centers.

 

i suggest to make that the character can sit down in the pokemon centers (at least, my character is tired to be stand up all the day, he stopped slepping)

While the immersion would be nice, this game doesn't need immersion. It's not likes it's a triple a title that needs some sort of realism, to appeal to its player base. It just needs to be what it is.
