imagine a new game, 8 gyms and shit
the 8th gym is vacant
the last battle with the rival is in the 8th gym and he is the leader
after you beat him he says that if you come back as champion you earn the title of gym leader
postagame you can customize the gym and do some achievments that triggers challangers
other gym leaders come to battle you
past games protags comes to battle you
you can create a badge

i think it would be nice
