Or, think of it like this: S-E has a brand that they're forced to live with. When faced with poor opinion, instead of abandoning the brand, they have to work extra hard to fix it. Thankfully, I think FFXIII-2 went a long way to saving the name.
I'm 100% agreed. I think XIII-2 was a great improvement over XIII, and depending on what they do with Lightning next, I may or may not be pleased.
Really, you can work with *whatever* franchise. Each individual game, with its story and gameplay elements, will be judged accordingly. This is especially true for anything Nomura touches. You can love or hate his character designs, but he isn't the one who makes or breaks a game. Proof positive: Parasite Eve series. First one is pretty rad, 2nd is ... well, people have mixed opinions on it, but in retrospect it's still pretty good. And then 3rd birthday is just terrible.
ALSO -- I don't know where the official source is for this, but I have it on good authority that at that 25th anniv. event, they will also be selling/releasing "Chips" albums for FFVII, VIII, IX, and X, as they did with FFXI with that "XI Chips" album released for FFXI's 10th anniversary a few months ago. And as far as I'm concerned, they can feel free to milk the arranged albums as long as the quality stays high. "Shut up and take my money" etc
