Nomura's answer, as always, is vague. Until they reconfirm the bit about Shinra and summon materia specifically, it's not evidence of anything. I'm sticking to the OG, as thats what the remake is about. You can keep repeating yourself, and you will not convince me otherwise, so drop it. If you want to convince me based off of just the OG, by all means, do so.
... There is absolutely nothing "vague" about "
Settings established in the FFVII Compilation works are newly incorporated and the story has been delved more deeply into."
Unless you have issues understanding plainspoken english, there's no way I can believe you can't understand a straightforward single sentence such as that. There is no ambiguity. "Settings" mean story, scenario, and lore. "Incorporated" means "made part of."
As
established in every Compilation title that depicts past Shinra, the
setting shows their warriors capable of using summon materia. Only you have an issue accepting what's literally already established fact. If you choose to go flat-Earther in the face of this fact, that's your choice but in the end, that's all it is. There's no real ambiguity or question about what that line means or what's been depicted in past titles regarding Shinra's capabilities of handling summon materia.
Because they don't use summons in the original game. An obviously good weapon and it is undeployed. They also do not sell it. Either they can't manufacture it at will or they do not understand it. Or they can do both but not profit from it. It can be any number of reasons, and it doesn't necessarily have to be limited to the ones stated. But it is not a given at all that Shinra can mass produce any materia in existance.
Guard Scorpions didn't fire missiles or release an EM field in OG FFVII either.
That never happened... Until Crisis Core when it fought Zack. So was the Guard Scorpion broken in the Midgar Reactor in VII when it chose not to use all it's weapons?
No. And here it is now, doing those new skills again.
There are
dozens of examples of changes that expand beyond what's shown in the battles of VII. Stop thinking that they're somehow going to limit its scope and capability because of what's shown in the OG, especially when every time since shows otherwise.
Even the Sunken Glenika that was carrying weaponry to fight Sephiroth carried
Hades summon materia. Again, you really think Shinra just got lucky in acquiring that materia? Summon Materia may be rarely found or used, but it
is used and used by the elite in Shinra.
Further, materia is about the knowledge of the Ancients. Something simple like fire or steal can possibly be easy enough to isolate and emulate per piece of condensed Mako. But an entire spirit of a near-godlike creature isn't the same thing. Neither is something on the level of Holy, which they would have had access to when they had Aerith and Ifalna in custody or even when they had her in custody later. That they overlooked it (and Hojo seems like the type who would have had Aerith thoroughly searched for "scientific" purposes) would imply they don't understand it. Even Aerith initially didn't (unless she was lying at the time, which is possible).
...Where does it say summon materia or summon beasts are all God-like creatures in VII? Summons of the level of Bahamut can be beaten by a SOLDIER 1st Class.
And considering Holy is so small it can hide in Aerith's hair and it is presumed useless by all until she discovers it's purpose in the Forgotten Capital.. Why would anyone
think to steal or study it? It's seen as useless junk materia.
On the subject of the reactors, do recall that the Condor Reactor's environment is similarly barren. The Nibel mountains also seem relatively barren compared to the nearby Corel range. I don't think it's a case of the environment. The more I think about it, I do think it's a design difference. The Midgar reactors are the only design we know of that is mass produced. Every other reactor in the game is a special snowflake. It could perhaps be a cost cutting measure that whatever process in the reactor would normally create huge materia is not present in a Midgar-type core.
The land around Condor however isn't nearly as depleted as "the Midgar wastelands." And Mt. Nibel is home to mako fountains where spirit energy
naturally wells up from the ground and condenses into materia. Just because the topography is rocky and dark doesn't mean the land is dead. Midgar's land is in a unique state of degradation.
