Personally, I would like to see VI redone the most. I liked VII better, but I have my reasons for why I think it would be a mess. In fact, [inserts shameless plug], I wrote an article on questioning if a FFVII remake would even work. I normally, wouldn't be tooting my own horn here, but it actually generated a good discussion at various places on the internet. Neither me or any of my friends submitted to Reddit, but I was told it made the front page. So while it is on my mind and we are talking about remakes, I might as well post it in this thread.
