So I should be studying (between losing and hour watching the video and checking on forums and stuff every now and then I'be lost some valuable time lol), but I'll post some impressions:
Starting with the negatives, I kinda dislike many parts of the game in regards to IQ: looks somewhat blurry and the AA is pretty bad at times. And some textures are pretty low-res, as well as some of the scenarios being too flat, visual-wise. The performance seemed much better than in previous showings, but still needs work. And I think that's about it. In a broad way, I really liked what I saw. I mean, I'm still iffy in regards to some combat, story... elements, but I can't really say much until I get my hands on this.
The gameplay looks pretty nice in terms of combat (I'm going to erase the fuck out of many of those HUD elements, though!), very flashy and, according to some people I've seen reviews of, pretty fun, better than in PD (which is only logical). The hunts seem alright, they're what they, well, should be (a little bit of story input would be great, but I guess random hunts for the most part are alright, too). I hope we also have some cool, fleshed-out sidequests.
I really liked the menu. It looks visually great, and the options regarding magic, weapons, clothes and stuff look pretty nice and engaging. And so does the map. I just hope the AP growth system is bigger than that. I know there are many other ways to define the characters, but I really like stuff like the License Board in XII if they're well done and the new abilities/buffs are intersting and fun to play with.
The alt clothes are funny. Hopefully there is a good number and variety. Older Noctis looks great, I really wish we could play with that design and clothes since the beginning, up there with my favourite FF main characters' designs (the hairstyle is great and not too goofy, his face looks a bit more mature, the beard/stubble is alright and the suit is pretty fucking cool). Hopefully we'll be able to use in NG+, especially since that scene seems pretty endgame and would be a same if they didn't give us that skin.
Regarding the story, well, we can't really say much (and we basically had seen/heard about the beats this video is about). I feel a little bit sad that we don't have such a heart-racing opening sequence as the originally planned one COULD (key word!) have been, as the scene in the hotel and everything Cor-related I feel lack some emotional punch. But again, I haven't played the game and it's obvious that this is a heavily edited video (for one, I think after Chapter 0 we have some time with Regis saying goodbye to Noctis. Unless that CG video is just in Kingsglaive or something like that. And we know there is (was?) a CG scene in which, in the middle of the road, Cor asked Noctis if he wanted to know the truth).
Oh, and the city looked beautiful. Hopefully those visual and performance issues are ironed out, as it's a shame such a great environmental artistic work is not represented in the bet way.
So yeah, actually glad, very glad about the delay, as much as it sucks and as ridiculous as this whole situation can be. And, also, as much as it kills me in the inside that I'm not playing it until February (unless a miracle happens and exams are abolished).
