While I'm pleased that they're updating the title and releasing it on PC via Steam, I have to say that I'm less than impressed. There are so many other Final Fantasy (and other Square Enix titles - I'd probably have an aneurism if they released an updated, high res texture version of Xenogears on PC!) games that could really benefit from this treatment.
Final Fantasy III's "3D remake" version is one of those that they've done well. Originally on the Nintendo DS, and eventually coming to iOS, Android, and Ouya etc.. this is a good paradigm. How about just bringing it to PC?
Final Fantasy IV is a fan favorite and I'd love to see the "3D, Nintendo DS" version, which I believe has the most extra content of any IV version, also brought to PC. Preferably, with options for Japanese vocals - I had to use a customized "undub" ROM in order to access them for the DS version. There is also "FFIV - The After Years", originally released for WiiWare (after JP cell phones) , which I would love to see remade in the same style as the "3D, Nintendo DS" version, which continues the FFIV saga. A Final Fantasy IV version for PC with high res polygon updates, and The After Years remade in a similar image, would definitely sell.
Then comes "The big one" Final Fantasy VI. If Square could put the time and effort of creating a "3d polygon" version of VI, with the better translated version of the JP script (as opposed to the US Final Fantasy III translation), with gameplay enhancements of both the Gameboy Advanced version and the Playstation 1 "FF Collection" version, it would be an absolute goldmine (affordably priced, of course). This cannot be a halfass attempt though, but it would be a MAJOR improvement just the same way the 3D polygon with vocal version of IV was a great improvement and upgraded the experience for a whole new generation of fans and caused celebration amongst old ones!
Final Fantasy VIII is one of the few with a PC version and like VII it deserves a similar update. I'd love to see some gameplay improvements as well, especially regarding the draw/junction system and more. One of my favorites for the reason it is one of the most controversial in the West - it is a Japanese-style love story, which has different cultural context than what many players were expecting.
Finally, Final Fantasy XII deserves an upgraded PC version. The acclaimed end to the series on PS2, I'd love to see the upgrades of the International Zodiac Job System edition applied to the PC version, along with an option for Japanese audio and more.
I'm a big proponent of all console titles being released on PC, so this is a good move. However, I'd like to see even more brought to light.
