SE needs to load up on the nostalgia value

I can certainly understand using music, weapons, spells, and names from the previous Final Fantasy titles but I don't think the inclusion of Antagonists from the other incarnations would work well. Square have always kept the games as worlds seperate to one another. Plenty of aspects carry through each (There's always a Cid, Biggs and Wedge occur in multiple games) but they've been careful to make the character unique to each "universe". Trying to pluck Kefka, Sephiroth, Ultimecia, Kuja, etc out of their respective worlds and just drop them into Eorzea would be detrimental IMHO.

I thought they had plans of some sort that would having Lightning making some sort of appearance. I'll have to ask my brother next time I see him. I could see them doing something like this since SE seems to think so very highly of her and ff13. I would much rather see Kefka make an appearance. They have magitek armor so at least thats some link they could use to work him in somehow.

SE will probably give us a new alchemist ability to throw potions and allow them to come as healers to dungeons or bedazzled coats like Snow had that make you more powerful depending on what bedazzle pattern you have on the back of it.

As I said, it would all be non-canonical and just fun little end-game features for the fans. And they've already added some FFXIII stuff: http://www.finalfantasyxiv.com/alliance/na/collabo/
