I got about 2 hours in. Knowing all the ins and outs of the battle system now from the tutorial you can do has blown my mind on how varied fights can be. It seems it is a game where you can't watch TV while you grind, because just smashing X the game will not play itself lol.
I'm busy knocking a few rounds back and forth on SF4 that came in with a buddy, but will try to get a more detailed consensus of the first few hours later.
1) Lip syncing isn't FF game quality, but it tends to be on spot for the most part.
2) Voice acting is great in English which is hard to say since most JRPGs this gen have not stepped it up in that department.
3) The dialogue is great. The few serious scenes have really well written parts and the few funny lines have been worth smiling or giggling at. Unlike something like SO4 where the funny parts make you feel sick to your stomach that you are "x years old" and playing something this childish for dialogue. *shudders at SO4 dialogue*
4) Battles are awesome! Nothing super hard yet.
5) World map system is interesting and leaves room for exploration in a unique way.(Look at OP and vids for more info on that, but I'm just here to say it is a great idea)
6) Creating items, customizing weapons, and changing clothes are all well done. My Zephyr looks like a totally hung over type of guy and Vashyron has this Michael Jackson moon walker style going for him. :lol The weapon and item creating seems like it COULD really lead to you need to have "x attachments" in order to beat this boss, because the earlier ones weigh you down apparently but give you more bullets or faster charging.(More on this later to see if it'll be a game where you hold onto everything you get)
7) NPCs in town are well voiced and although they usually have only 1 line of dialogue it isn't too cheesy or without feeling like that person belongs where they are.
8) Every piece of music not only fits where it's put but is someones best work ever as a videogame music composer. Big props to the person in charge of this soundtrack.
That's about all I can comment on for the first 2 hours, but the big thing that's got me so blown away is even with all the info about the battle system I had and the demo experience it's still insane to learn all what the tutorial covered that I had overlooked. Things like cover shooting, raising enemies into the air for extra turns, then smashing them to the ground to break parts and extra damage...any RPG fan will fall in love with this really fast I think.
