When you remake an old product, and/or adapt it to a new medium, there are two approaches you can take. You can opt to completely rehash the original, adding nothing new to the overall experience, using the same storyline, same graphics, same characters, whatever, while still trying to update it to modern tastes, in which case you produce a product which is generally inferior to the original (a la MGS: The Twin Snakes) or you can opt to take something that everyone knows and loves in a bold new direction, still keeping some characters, story elements, etc. from the original, and most importantly still keeping with the spirit of the original, but creating something that is fresh, shiny, and new. The best video game example of this is the Gamecube remake of Resident Evil, but anyone who has seen both versions of either the Mummy or Invasion of the Body Snatchers will also know what I am talking about.
While a port of CT will certainly be nice, I'll probably buy it at some point, it just frankly doesn't excite me. If squenix would produce a new twist on this classic, even if it was a terrible gameplay gimmick that everyone hated, it would at least be a fresher experience than the same game we've all been playing for almost fifteen years.
If you ask me, Squenix really, really needs to stop re-releasing their games right now. I'm sure the thought over there in the Squenix offices is that these ports will introduce a new generation to the game with minimal work on their part, but realistically, all the people who didn't play CT (or Valkyrie Profile, or FF's I-VI, or any of the other stuff they've re-released) when it came out, but wants to play it, simply downloaded a ROM and Emulated it. For the most part, the only people buying the re-releases are the diehard veterans who have already played these games a thousand times, and frankly, I haven't bought many of them, and Squenix will quickly lose me as a customer if they can't start exciting me with new products again.
Sakaguchi leaving doesn't have to mean the end of all things good in the company, but the others still within the company don't seem to feel the same. Which, of course, brings one to wonder the age-old question: Is Square Dead? (Sorry, I just couldn't resist :-))
