13 is like... they have a map maker, and just thought of a bunch of different map ideas. they had a button to say insert treasure ball, and many treasure balls there was. they had a button to say insert "all-in-one save/shop/upgrade station" and many "all-in-one save/shop/upgrade stations" there was. in 7, they actually had real shops you would explore, and they didnt shove every single shop, save point, upgrade service, and whatever else into one identicle terminal, and put 50 of those same terminals all around the world. ff7 in a whole was just really expanded with plenty of places to go. and im not just talking about how many maps can you make with the same exact map maker
