the game cant be changed in its base so that it don't lose it taste , but the add in every 3 new titles
there wasn't berries in blue , red , green
there wasnt GTC even pokemon plaza
it may look the same but its not
and its best they keep the same roots but not the same branches
and the make 2 titles at first in order to make ver exclusive pokemon
but what you are right in is the 3rd title in better way
