- The Introduction of the newest trailer was CG, but everything after that was running on the PlayStation 3 in-game. This includes the ending segment when the characters talk in the dark room, and when Noctis' father is looking pissed at the priest.
- The current voice acting cast is being kept secret, but some hardcore Nomura fans have figured some of them out. Get hunting on looking over the VA's from Kingdom Hearts.
- Famitsu asked just one questions about the Fabula Nova Crystallis mythology. Will the l'Cie, who were depicted in Final Fantasy XIII as humans given the power to use magic and summons in exchange for being burdened with a mission, appear in Versus XIII?
- Nomura confirmed that as Versus XIII is based off the same mythology as FFXIII, the term l'Cie and other such terms will appear. However, going along with the modern look of the world, the language used in the conversation will also be modern. He didn't explain what this means precisely in terms of the use of the phrases.
- Double Jump, limit attacks, magic, all the basic Kingdom Hearts jazz is there.
- The icons of other characters aren't just cosmetic. It's to help you gage what they are doing and are rendered in real time. So whatever face the character is currently making, you see that same face in the HUD.
- Magic can only be cast when Noctis is in the party. What this means, who knows...but it's related to the story.
- The Final Fantasy Job System returns to Versus XIII...but only enemies will be using them.
- The Kingdom Hearts "Special Team Attacks" are gone, but you can do them manually. You can't do it from the command list anymore. :(
- Each character plays differently, while Noctis will be the "Jack of All Trades".
- It works like GTA, the majority of the maps are open ended...yes...Nomura was telling the truth. They managed to scale a proper 1:1 World Map in this game.
- Day/Night Cycles Are In
- Biggest In-Game World, aside from Final Fantasy XI
Six years already, and Nomura has kept every promise so far. As one of the last remaining talent from the original Squaresoft, I'm surprised the game is turning out like it is. It's like Nomura wants to fix the past sins of Square Enix.
tl;dr - It's Kingdom Hearts, but for adults.
