Duraframe - that's fair. I think you're right.
I think the original game had a lot of unresolved tensions around the juxtaposition kaisergeddon mentions, though. On one hand I liked how Shinra starts out as an overwhelming totality, but is shown up as a tiny speck in a world that in many ways remains untouched and not properly understood by Shinra. On the other hand it stretches the imagination when Shinra apparently have their hands deep in Gold Saucer, Wutai, and everywhere else, but even a village like Kalm next door seems pretty peaceful and unbothered. Honestly, I don't think the writers had it all figured it out, I think it was partly a byproduct of typical animu "oh bad guy X turns out to be just a puppet of supernatural extraordinary bad guy Y".
Hojo is the figure that maintains a more interesting set of connections between Shinra, Sephiroth, Jenova and the world, of course, as well as Aeris, Vincent and the Prof. Guy is the true thematic glue for the game beyond Midgar.
