I don't care that the games aren't the same as they were in the 90s. From my point of view, 12, 12:RW, TA, and TA2 are all sequels to the original FFT, because they all take place in Ivalice. They essentially retcon the events of FFT though. Despite the work of Alazlam, no mention is made of Ramza, or even Delita. The Zodiac monsters are still alive, and seemingly unharmed despite Ramza wiping them out.
The entire landscape of Ivalice is changed. If you compare the various games, none are visually similar to FFT. My main beef is with Tactics Advanced, and Tactics Advanced 2 though. They are far too light hearted. The original FFT is at its core a dark fantasy with very adult themes. There's nothing wrong with games that are more light hearted or kid friendly, but I do not approve of a genre shift for an already existing franchise. It'd be like turning Lord of the Rings into a comedy, or Star Wars into dark fantasy or steam punk.
I actually approve of the direction most Final Fantasy games are going these days. I'm very psyched for Versus 13, and I think 13 and 13-2 have kickass stories, and Caius Ballad is a beast. I don't approve of 11 and 14, but I dislike the idea of an Elder Scrolls mmo just as much, and for the same reasons.
I just don't want any more games taking place in Ivalice, they've fucked up the lore enough already.
