The FF remakes keep the core game/story elements and expand on them. Think of the original with A LOT of padding.
For people who have played it since the PS1 days, it can be a bit tedious, because you know what's coming, but there's so much more stuff in between before the main story continues, and you just want to advance in order to see what Square Enix offer next in terms of presentation.
For example, I can't wait to see how the KOTRT summon turns out – or to encounter the Weapons.
