I was chatting with a friend about the issue of world maps. Brought up gold chocobos, and how ridiculous it would be to use on anything other than a representative world map. Just running completely over buildings.
My friend only played the original for the first time very recently (because I yelled at him to a lot, and then i got to watch him). Something that really stood out to him was the wutai sidequest. The way you can just stumble into it organically. Then, it doesn't force you to do the sidequest, but, you know you have to. You won't get far without any materia. My friend really likes world maps. I think it might end up looking very silly. Nice graphics only exaggerate things like the issues of proportions. Large expanses of land without civilization and the ancient's key being larger than the submarine. They could do a FFX world map deal, where it's a literal map and you tell Cid, "go there" and off you go. But in my opinion, that takes away all of the excitement of exploration.
I personally would LOVE an open world deal, even if it was a compressed world like in FFX. I love feeling like I exist in a space. If Midgar looks so tiny that I can actually see the sky from anywhere, like in CC, I am going to be very disappointed. But, I also know in my heart that the image of the ideal open world I have in my head, that I want SO BADLY, is probably not something they're capable of at the moment. If I had my way I'd be spending hours assassin's creeding my way all over and around the streets and buildings of Midgar, but they're not going to spend that much time just focusing on what I want.
