Will definitely disagree about FF XIII as being "episodic" in the way Xenosaga was. Love it or hate it, XIII was at least a complete story, whereas Xenosaga Ep1 ended part way through the story and it wasn't even a huge important arc. It was just getting from Point A to Point B and explaining some stuff on the way. You had the same base cast continuing to be important after that. Whereas Fang and Vanille were done after FF XIII, and most of the rest of the cast should have been done, except then the Etro stuff happened, which is at least a new conflict that's not contained in XIII.
On that note, I am now much more looking forward to FF XV than the VII remake. The ATB is generally pissing me off more than the episodic news, since I'd love to see a real attempt to make a proper go of the old FF7 combat system. The FF7 system had huge potential, and a remake is the perfect time to make it better. Arg. So, yeah. Also, with the Crisis Core stuff I know they can keep the old FF sensibilities, but I'm always afraid they won't. And Cloud in particular is someone they seem to be good at not getting, so I'm kinda worried about that.
Combine that with just being able to play the original, well, I'm dreading the remake as opposed to just incredibly apathetic about XV. And hey, I was also really apathetic and then disliked XIII a touch before it finally grew on me, and now I'm a fan of XIII, so maybe XV will manage that same trajectory. There is a touch of hope there.
