To move away from speculation of story and the doom and gloom of the combat system details for a moment, I'm quite excited about the world design aspect, even if the game's about to knock on the door of WRPG territory.
+ Camping; this is reminding me of both The Witcher (only presumably without a crafting feature) and older Final Fantasy games. I'd kill to see Noctis and company suddenly hole up next to a picturesque river with a giant Moogle-themed tent as Ignis and Prompto attempt to work the George Foreman grill. Intriguing, original idea to have camping be necessity for next day performance as well, and I don't believe that's a feature in an RPG I'm familiar with - at least not one I have played.
+ It's open-world, but not quite open-world; that's the sort of design I've been expecting. No one realistically expected Skyrim, but in terms of zones, and interconnectedness, it will still be expansive enough to allow manned car travel, reflecting a natural evolution of the world design FFXII began with. It's a perfectly good Goldilocks zone between openness and structure ripe for narrative progression. Of course, FFXV's middle would have to avoid meandering and spinning its heels like FFXII's.
+ Seamless connection; if this is actually the case (it would have to be, otherwise it would be jarring to have to see your car disappear through a line of glowing blue circles to get into a new zone every time), and I don't know how technically possible this is, or what the game's actual scope is, but this is the thing that has me excited the most. FFXIV: ARR would have been excellent, had the game not thrusted us into ubiquitous loading screen transitions here and there - where getting into Minfilia's Solar is bad enough.
+ Weather; and its effects on elemental spells. I'm not sure how I feel about your fire spells being extra deadly on arid days that you can start a friendly fire barbecue without the need of the George Foreman though. Hopefully that warrants extra tactical thinking during the supposedly rather automated combat. But setting Ignis on fire sounds almost meta.
+ So it's a continent? Sounds sensible enough. Realistic game world size speaking, no one was expecting an entire world - especially if they're still sequel baiting - but I wonder how this affects airship usage. If we can still use airships, which I don't recall seeing any mention of?
tl;dr - world design sounds good. Sounds like my ideal sort of RPG, and it's something to remain excited about, while combat is giving us all consternation.
