Ooh, yeah, I have to agree with Agita in that I'd love to see a more interactive environment.

Regarding BG-57 and how an entire world limits sequels: So? I would much, much rather another FFVII/FFVIII styled game than a FFX with "oh but you get FFX-2 too!". Uuuuurgh. Final Fantasy games should never be designed with a sequel in mind. Also, I don't see how it limits sequels - FFXII? Limited world - no sequels. FFVII? Entire world, more sequels than a lot of people could tolerate.

Also: Jumping. This would actually satisfy me when it comes to interactive environments - if you could jump up onto boxes and so forth, that would be half the battle when it comes to being able to do more.
