I liked FFX, but does it really need to be remade/re-released? There were a lot of great elements and I wouldn't mind if a future Final Fantasy game borrowed from the FFX battle system a bit. But it's not so old that the people who remember it probably don't still have a copy. I know I do (somewhere) and if I really wanted to play it that badly, I'd just dust off my old copy and play it. Still, there are worse things they could do.
And since there is an underlying topic here. Honestly, I'm not even sure I want them to remake FFVII. And I'm a fan of the game. I just don't know if they could remake it without trying to tweak it a bit. And then what would we end up with? And that goes for other old school, but not quite that old, Final Fantasy games, as well. Yes, I'm thinking of FFVI, FFVIII, and FFIX in particular.
