It's not about rewriting VII as much as it's about pointing out how they wasted a perfectly good plot for something simpler. It's part of the reason why my favorite games of PS1 Square generation are generally the non-FF titles, because they did push for something more complex and thought provoking. Even FFXII is a nice step in the right direction despite being badly diluted from the usual stories that Matsuno wrote. Part of why I feel FF seems to be left behind by older fans is because their set of ideals for the series refuse to grow despite their core fanbase doing so. One of the reasons why I feel WRPGs have grown more popular is due to being willing to tackle more complex and difficult topics and scenarios, whereas JRPGs still hold onto more conventional tropes due to a fear of lack of familiarity. Even though JRPGs do hit a wide spread of different topics and themes, it's interesting to note that most series still stick to a sense of familiarity within the series own context.

My point is that VII could have been so much more (not that the rest of the series isn't guilty of this as well) and why I always felt the Shin-Ra were a more intriguing villain than Sephiroth.
