Love:
The character gestures are incredible.
The map looks reasonably open. Even if the teleport move is locked to certain points, so long as the map is open for foot traffic I will think it's good enough.
The story looks thusfar like it nails the balance for FF games; tense and character driven.
The music. I have loved Yoko Shimomura's work since she did Parasite Eve WAYYY back in 1998. I look forward to her FF soundtrack.
Worried about:
Those character gestures are a bit TOO good. I have to wonder how much is actually prescripted. If it's legit XV will set the bar for next gen RPGs. I don't think it'll be that good.
The Story. FF games always feel like they're filled with half-baked ideas and need another draft. I'll believe this one is different when I see it.
