I'm sorry, I am going to have to loudly and obnoxiously disagree. Bear with me as I rant and rave...
If you are a peasant in a rural medieval-style town like Nibelheim, the names of food ingredients are some of the only things you are guaranteed to know. Especially when you have a single mother and no friends.
No where is it established Cloud learned, or even
had to learn any of that. His mother babied him, and even told him he needed a nice strong woman to take care of him, since he wasn't one to really take care of himself.
Moving to Midgar at thirteen required a trip across the globe. There was no shortcut through war-torn Wutai. At a very young age, Cloud had to learn to fend for himself or at least operate inside of a small caravan of young SOLDIER hopefuls. This would necessitate the basics of survival, which include knowing the names of fruits. And when you are travelling around to a whole bunch of different towns, priorities are figuring out what those are and acting accordingly.
Cloud joined the Shinra MPs before the war with Wutai hit its peak, at 14. Hell, he never really saw any action in Wutai at all. I'm not sure what a shortcut through Wutai has to do with it, seeing as how you don't have to pass through Wutai to get to Midgar from Nibelheim. Where does it say he passed through a lot of towns either?
And considering Shinra provided most supplies and basics for him, it's not like he had to even do survivalist training. He was stationed in Midgar as an MP. He wasn't a special op who saw much action at all, anywhere. He was just a grunt stationed first at Midgar, and then Junon. Those were the only two places he got stationed at in his short stint as an MP.
Next, arriving at Midgar and entering into the Shinra military would necessitate some kind of living situation, probably Shinra-owned, with a small kitchen and a few roommates. For three years before the Nibelheim mission, Cloud was responsible for himself, and for keeping himself in top condition, and that requires training, which requires nutrition. He was a grunt which means that he doesn't have mako or Jenova enhancing his abilities, he only has sheer will. Cloud is the kind of character that would learn how to adapt to urban life, and that mean produce stores.
Again, that's your personal
assumption. He's only a 13-14 year old kid. A child soldier. Expecting to him to be some survivalist prodigy when he still hasn't mastered the art of socializing or talking to girls seems a bit much. Going by the cozy, cushy conditions of the Shinra building and how SOLDIER and MPs got to live in their dormitory living situations, there isn't much credence to the idea that they had to adapt to urban life very much. Most of the things they need came from freaking vending machines or a cafeteria.
And in Midgar, where produce is scarce, it would have been a priority to figure out which ones contained the essential nutrients to continue life in the Shinra military. This is one of the only things that soldiers have to worry about.
...Who said produce was scarce? Maybe for the poor fucks in the slums, but the top of the plate, Sector 0, where Shinra's elites live, is a very wealthy and comfortable area. The people who actually are part of Shinra and important, have no idea just how good they have it compared to the otherside of the plate.
Next, Cloud spent five years in a tube. Sixteen-to-twenty-one. How many fruits did you learn about in those five years of your life? It couldn't have been all of them...
Afterwards, he travelled the whole world again looking for Sephiroth, which took months at least, and after that he had two years of settling down and trying to rebuild a barren earth, and that means at least being aware of agriculture. And now he can't understand a shopping list.
Umm, considering your teenage years give the foundation of most of your adult life in terms of life skills and knowledge, suddenly going from 16 to 21, with nothing inbetween except a false reality would kinda make adapting to normal life and responsibility difficult. Especially if you're expected to know which fruits/vegetables can be used or are necessary to make alcohol. Which I'm sure isn't something that was within his personal sphere of importance in the first place.
Most teenagers begin to learn the life skills of adulthood when they reach the age of 15 to 16. From then on, they build upon those experiences and learn to be independent. Cloud essentially went from childhood to adulthood with none of the transitional teenage years to allow the transition to go smoothly. Learning how to cook and fend for himself independently isn't something one masters at the age of 14 to 15.
I understand that we are letting them get away with murder in this Compilation business because at this point what is the use, but we should not be defending this fucktarded detail. If you want an interesting detail, why not say that Cloud can't write? It's not a skill everyone in a fantasy world knows, and Cloud never does it in the game, and it's not completely fucktarded. Or why not say that he doesn't understand alcohol? Or he loves his bike but doesn't understand it so he has to get Cid in once a week to check on it? All feasable to me.
There's nothing fucktarded about it. Somehow thinking that spending 5 years as a braindead meat puppet and then having your actual memory completely muddled by an alien's cells, wouldn't negatively impact your ability or knoweldge on how to cook, or interefere with how to live a normal life is just ridiculous.
Cloud demonstrates reading, drinking alcohol, and other things in FFVII so your comparison's baseless.
