Duscae was 720 right? And less detailed than the full game will be? And dipped down to less than 15fps at times?
No, it's resolution was 900-something on PS4 and 720 on XBone. Even 900 with the right antialiasing technique can look really good, like in Star Wars Battlefront on PS4. Tabata confirmed antialiasing will definitely be added and they are at least trying to get the game to 1080p on PS4 with stable 30fps. I have no doubts that in the end they will be able to make the game look at least "good". It's Final Fantasy after all... They are huge graphic whores. XD And don't forget, a few months ago Sony unlocked the 7th processor core for developers on the PS4. This will give the system an additional boost in graphics which even furthers the gap to the XBone. The XBone version might look a little rough though... :/
I've never seen this video and you always manage to post things about this game I haven't seen. I love how much wildlife there is in this game, I could just walk around looking at the animals going about their day for ages. And yeah I kind of don't mind if the story isn't that great at this point I just want the game to experience the world and game because one of my favourite things for any fantasy world is getting deep into the lore of it. Also I hope there is lots to do and see in the cities so they don't get boring like side quests and stuff that introduce minor characters and little tidbits of lore.
Lol, so what else haven't you seen yet and I'll immediately show you!

It's funny, they showed a lot of stuff of the game already, including a whole game region to play in (Duscae) and a lot of people already complained about that. Too much info for them apparently. (I personally can't get enough!) On the other hand there seems to be SO MUCH they didn't show us yet. Even I actually don't have a clue what the game is going to be like in the end. Just that it will be at least very beautiful and polished in it's art and design.
Concerning side quests: I would always be wary with JRPGs. :/ Even most Western RPGs still don't get it right. But there is one glimpse of hope: Tabata a while back said, that he and his team would consider The Witcher III as the paragon of RPGs at the moment, so they might have been inspired by the formidable quest system there a little...? The Witcher has by far the best side quests in any RPG. There is simply no "kill monster X or bring me item Y". All the side quests in this game have an interesting, little or bigger story attached to it. It's never a chore, because you really want to learn about the characters and the world and the mystery you might be unraveling.
Concerning the main characters (even though you didn't mention them, but I'd really like to say something about them too. XD): I can totally get that quite a few people are put off by the mere look of that Jpop/Kpop group...
...and I was on the fence about that too. I really don't like these pretentious, brooding emo-type of characters but they are not like this at all in the demo, phew! u.U Yes, they don't reinvent the wheel and they are based on the typical JRPG/manga/anime archetypes...though let's be honest here for a sec: We JRPG players, manga readers and anime viewers actually love those.

They don't seem brooding and emo-ish at all. No, they are actually funny. All the lighthearted banter and even very small interactions between them are really cool and once again an example of the extreme polish of the game. If you for example go into the water and stand still there for a while Prompto (the blonde guy) is like:
"Going for a swim?"
And Noctis will mumble: "Nuh, just a dip..."
That's so funny and random to me and life-like. XD
They are really the best of friends and they care for each other and they are (THANK GOD!!) also not of the extremely cringeworthy "Dudebro" type, that's now so often apparent in Western, (specifically American) games and media. As a European I find that bro/bruh affected behaviour so awful! D: No close male friends act like that in reality...or do Americans actually do that...?
All in one they are really likeable if you just see past the Louboutin boots and the anime hair. ;D
