Sorry Shamus, but the thesis of your article is absurd and proves that you don't fully understand the topics you are discussing. No serious or knowledgeable proponent of a Final Fantasy VII remake has suggested that it would not be an enormous undertaking. Of course it would be, but so what? That is what commerce is all about. Companies invest vast amounts of time, resources, and money into creating a product and then recoup their expenses by selling that product. You remake-deniers act as if they would be doing it out of the kindness of their own hearts. They would be doing it because it would make money for their shareholders. Unlike a Final Fantasy XIII, which is a financial gamble, a remake of Final Fantasy VII would be a virtually guaranteed investment.
This whole idea that "they don't make them like they used to" is ridiculous. Have you not played DragonAge: Origins? Elder Scrolls? Assassins Creed? MMOs like WOW and FFXI? Heck, The Old Republic is being marketed to be easily 10 times the size of Final Fantasy VII.
An FFVII remake would require nowhere near the level of complexity seen in other modern games that, according to you weren't "made like they used to be". There's no customizing of characters, no branching morality changing the way your character is received throughout the game. Everything is scripted and linear. Yes, they would need to design an enormous world. But such a thing is done in contemporary game design on at least a monthly basis. They would also have the option of incorporating a more linear travel system if need be.
If you want to offer a compelling argument for why a FFVII remake is improbable, I'm all ears. But you'll have to do much better than this.
