I am playing it right now...
here is the thing... they have expanded the game to include way more quests.. the areas are much bigger with side quests to do.. the characters are still the same but now they have way more dialogue so they feel more alive and real with more personality
they really did a good job making Midgar feel huge.. like a real city.. feels more like you are part of the city like in the Advent Children movie.. because Cloud is more connected to the people around him... in the original ff7 game cloud felt more stealthy and loner, that nobody really knew, but now hes walking around interacting with everyone he meets...
Midgar used to be done in the original game within a few hours... but now there is so much more to do and the zones are much bigger, so it feels really alive, like the capital of a continent should feel like...
so it's just Midgar as far as i know... so those first 2 hours from ff7, has turned into a 20 - 30 hour experience
and i love it
will definitely buy the sequels
