Now I'm going to have to play it again, because I can see everyone online calling it the sector 5 slums but I could have sworn it was identified in game as the sector 6 slums.

What if they let us play as Reeve in the upper city? I doubt it, but it's just a thought on how they might incorporate more of the city.

One thing they could definitely add is the ability to go see Loveless instead of just having Cid talk about it near the end of the game.
